I get you :) Not sure whether you believe in God or not, but I find this prayer very good for me, maybe it might be of help to you:

To accept the things I can't change.. courage to do my best to change the things that I can, and to accept what is how it is, not in the way of feeling defeated, but just as is.. Enjoying one moment at a time, living one day at a time, not focused on the future and my insecurities.. that life is hard but hardship develops endurance and resilience for harder challenges down the road.. accepting the world as it is, not in that I like it, but it is how it is and my wishing it weren't won't change it, but we can do things within our abilities to make it a better place..

This prayer helps me to I guess 'center' myself, when my head is buzzing and I can't think or feel straight, it helps me to clear up my focus.

Though, as someone who does believe in God, it 100% helps to know that we're loved, accepted and in Christ Jesus have security, even if we don't feel like it, even if we can't see the path in-front of us, we're made with a purpose and we're never in it alone.
