Well, the first advice I have is try to take it easy. On yourself, on others.
I heard this cool idea that we only think we trust people anyway, and that what we really have is belief in our judgement of people.
So when our judgement is wrong about them, they hurt us, they aren't who we need, they abandon, etc....
We picked them, and we need to not get so wrapped up in our judgement of another human being, or reliance on a human being.
Turn to God.
Pray about it.
I hope you feel better about this soon.
You've got your book, you've got God. He is the answer. People can point us in the right direction, and I'm in AA, but the program, which I think NA is modeled after teaches us that God solves the problem. Lack of power is my dilemma.
I'm not going to get the power from someone else. I've got to connect with God.
If you feel you need someone to direct you...find someone new...it's alright.
