Megan,
Welcome to SR! It sounds like you are going thru some tough times right now, and that you don't have a very strong support system around you.
My own recovery has taught me that I can love some people even though I cannot trust them or depend on them. I've had to make some changes in my friendships - those people I turn to when I need help and those whom I am willing to offer my help.
In some places they call it "going to the hardware store for bread" when a person continues to look for something in a person who just isn't able to give it.
What helped me was to get involved in my own recovery. I've made some wonderful, trustworthy and life long friends in my Al Anon meetings. I'm better at choosing friends, and I am a better friend to others.
Read around here, check out the stickies. There is help and support here if you want it.
