Hi, I am Bill, pleased to meet you; God simply bless you howsoever He pleases. I tend to give Bible knowledge answers; others here have already given very good things to help you. So, you can consider what I am about to offer, but most of all others have already given some extremely good and helpful things. So, most of all, just be encouraged, get the correction we all need from God. You can feel like you are some special case, but all of us have been like you, somehow, and if any of us have gotten into peace with God, we know it is thanks purely to God, and we have not been somehow superior to you or anyone else, but thank You, O God our Heavenly Father.
So, let me offer some things in a little bit of detail, in case they can help you.
Things are getting more tense in the family. Well, at least for me, anyway. I am stuck with them until the end of August. None are Christians, which makes it rather difficult for me. The problem is that I've simply had enough. I wouldn't go so far as to say that I hate them, but I would be happy if I'd never see them again in my live.
We all will always have impossible things to deal with; so may be we could say there is no hurry to make some present hard social or family thing go away. But get with God about it, and even use it for His good purposes, so we learn better and mature more in how to love, including how to please our Heavenly Father.
Instead of being mainly concerned about how to satisfy and please our own selves . . . we are here first for pleasing our Father in Heaven.
The problem is that all these emotions I keep holding back are taking a massive toll on me.
yes
Ones say we need to have an outlet for our hard emotions. But I now understand that God is able to totally remove whatever is not good for us; we do not let it come out in some way of expressing it, but with God we get rid of it.
"Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice." (Ephesians 4:31)
You are not ready for this, ones will say. But we all are not so spiritual like we might like to suppose. God is the One who is spiritual enough and almighty to put away what is damaging and conceited and nasty and degrading and dominating. Jesus is "gentle and lowly in heart, and you will find rest for your souls." (in Matthew 11:28-30)
Consider how it was like for Jesus who is so real and right and tender and kind to be with His disciples and all those enemies, so much of the time. Yet, Jesus did not give up on any of His disciples, then Jesus suffered and died like He did on the cross, with hope for any evil person, at all.
So, Jesus is the One who can make you able to handle it.
None of us can, without Jesus.
I am always on edge, I tend to explode in private at the slightest provocation, such as losing in a video game or simply misplacing something by accident. I have already broken several of things and it isn't getting any better.
Ok, so you have made yourself clear that you know you have a problem.
Even so > I will say > this is a problem!! And when I can give in to being nasty against innocent things and people . . . I am my real problem, right? And even though I know this and admit this, still it can be frustrating to keep getting proof that I have not become real with God the way we all can be.
God's best blessing for us is Himself through Jesus, and where was Jesus? > right in the middle of selfish disciples and horrible people.
I have trouble focusing on God through all that pet up aggression and the constant feeling of restlessness makes it impossible to do things that matter or even react adequately towards my family.
I understand you do not mean "that pet up aggression", but "pent-up" aggression. Even so, you might have made a revealing mistake here > how you are allowing that aggressive stuff to be a pet. It won't be animal cruelty if you neglect and starve it!!
When you are getting aggressive, don't you also have a feeling that you are entitled to something? So, this can be a pet thing, how you feel things and people have to be a certain way for you > your way!! We need for God to get rid of that pet!!!!
I also fear that instead of teaching me patience, it will instead cause long-term damage and turn me into a passive-aggressive seclusionist.
It is an abusive pet.
I assume, it is getting worse because I am this close to leaving them all behind.
It is better to leave your own self behind > we are our own main problem, and Jesus knows this so He has said >
"If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me." (in Luke 9:23)
So, we need to be encouraged how our Heavenly Father is committed to giving us real correction > Hebrews 12:4-11 < and so, do not be afraid of this problem but trust God who is almighty to be able to change you into how His love will have our character be.
