Hi tee tee,
Welcome to the forum.
You are not alone. I'm a worrywart too!
I try to tell myself that whatever happens in the future is out of my control. I won't worry about it now. Just let it be. I'll deal with the problem when I'm faced with it.
If that doesn't work then the waiting-game is my last resort. Just "ride it out" and wait for the bad feelings to pass. The rough moments will pass. Good things may be waiting for you in the future but you just can't see them yet.
I hope this can help you.
