It is so hard to learn how not to worry. This is what has worked for me the best, as I stuggled with this
a lot in the begining.
Jesus has to be your absolute focus. Nothing else can matter to you as much as your personal relationship with Jesus. I am not talking about screaming from every roof top to convert others, I mean in your heart, in your
soul, you must keep Him close with prayer.
After this is accomplished you must realize that even if the worst thing happened no one could take your Lord away from you, and since He has become the most important thing to you, then things are not that bad.
No relationship is as important to you than the one that you have with Jesus, and through Him, with your Father.
The only thing that you can do, as far as any human relationships are concerned, is to be honest. You can't make anyone feel a certain feeling or do a certain thing unless they want to. All that we control is our own selves, and nothing and no one else. If someone hits me with their car, I can not blame God because He did not hit me with a car, another human being, in full control of themselves, hit me with a car. All that I can do is remember that my Lord is with me everyday of my life, no matter how wonderful or how crappy that life is, and after this life we have eternity with Him in paradise.
I hope that this was not confusing in any way, if it was feel free to question me
