Hi, Flavius
So, what are you studying in school?
and losing at games I typically want to enjoy playing.
If you face a challenge that is more than your level of ability, then yes it is likely you will lose and make mistakes. So, you can go to a level that is easier while you learn. And once we learn to overcome that challenge, then we are ready to take on something greater - - even though it may beat us, at first. Maybe you are too ahead of your level of ability, "or maybe there is something much more worthwhile that you need to be doing."
If we play chess against a top ability setting on a computer, surely we will lose. If we set the computer to zero ability, the computer will give its queen to one of your pawns!!
May be you are taking on more than what you need to start with, in order to develop and make progress. Also, we Christians understand that not a one of us, Flavius, has the ability to do anything really right, unless we are with God. And God, Flavius, is personal with us; so yes He is personally interested in you. And I have been through all the wear and tear and wringing of not being with God and seeing how frustrating and awful and scary this is, with me trying and failing.
I was sure I would be a teacher, but I was clueless about relating with people. So, of course, I did not make it as a teacher. I needed to start with learning how to love and relate. And this has taken God.
I can't enjoy myself because the moment I lose once I'm filled with hatred, anger, and self-hatred.
If we base our happiness on what isn't going to happen, we won't be happy! I enjoy doing photos. You can see a couple in my album, here in Christian Forums. You might notice I don't have people and pets and wildlife . . . because they pretty much are not available. But I can find flowers and weeds

So, I enjoy what I've got.
"be content with such things as you have", we have in Hebrews 13:5.
This is my rule, also, for what I have with someone in a relationship. Only after I got into this principle have I gotten into a really affectionate and satisfying relationship; but it took years of investing in dealing with how the Bible says to relate and trusting our Father to correct me into real loving, which still needs plenty of correction; but we help each other, instead of demanding what one of us is not ready to produce.
Like this, if you demand what you are not ready to do, of course you can fail and get frustrated.
"Start with loving~!!!"
It's made all the worse when I realize how many people can actually have fun with the games I play whether they win or lose.
Well, there are football players who have fun getting a Super Bowl ring, but how long do they last in good condition? And how well can ones handle their money and relating with their wives? And how does such high-emotion competition effect the development of their personality to become gentle and humble for family relating? What good investment is it for finding out how to love? Like the issue of what football competition does for someone, what really can gaming do for you . . . even if you win?
The hardest thing to do is to find out how to love in a relationship. If you feel like a loser, look at the divorce record in the United States!! Every one of us has been a loser, without God, when it comes to finding out how to love.
But it is possible with God, and one of our main worthwhile investments. And this is something God is committed to doing with us, Flavius. So, if we choose to seek impersonal and less personal things, including like competition, this can keep us from connecting and being personal with God . . . because we are going a not personal way.
And anger is a design play to keep us distracted away from finding out how to share personally, and do this with God. So, yes anger is destructive, like I think you are discovering and saying. But only God is able to make us succeed against anger. It helps to confess that my anger is a problem, and it helps to look to God for help and healing, and be open for who can help us . . . even though there are plenty of people who have not been helpful.
Then there is the fact that this should be the happiest moments of my life where there are no extreme stresses of life, living without fear of paying bills or those responsibilities and yet I'm miserable most of the time.
A child needs to grow, Flavius, before the child can get a clue what the child needs to learn. A three-year-old can't "get" that he or she needs to learn algebra

So, you are now developed enough to know you have some things to discover, about happiness and dealing with anger. There are people who are maybe even successful in making money and being famous; yet, they do not have a clue that their anger is a problem > their pride has them clouded. Be humble, offer yourself to God.
I don't feel I have what it takes to survive in the world, I just want to lay in bed until I die. I'm suppose to be happy and stress free, if this is the happiest days my life how miserable will my future be? Even with all the support around me suicide is always a frequent thought.
We could be comparing ourselves and our success to ones who are not really happy but only are showing it, Flavius!!

Don't go by how things look, in comparison to others > do your own discovering, and enjoy sharing.
In fact all the loving support I have seems to just prove my point, that without them I'd die on the street a talentless loser who will never accomplish anything.
Oh, so you feel a little "dependent"? In the United States, independence is the downfall of many people, so they can't share in their marriages, even. I have found as a Christian, how our Father wants us to need one another, to depend on each other and enjoy being this way . . . so we can be family. So, if you have caring family, this can be very good.
And none of us had anything to offer Jesus. But Jesus the best One is not conceited about being so superior to us, but He wants to share with us as His own family. And we discover how we really can be good for one another. For me, it mainly is just loving with each other, not me being "needed" or some great smart counselor, but just appreciate having ones to share love with. It has taken me until age 67 to kind of get started finding this out. God often gives people more than twenty or so years, for a reason

He's been around longer than any of us have
So, I trust You, God our Father, to encourage Flavius with us all, and we all need how You prepare us and teach us and correct us and strengthen us in love.
