Welcome to PC gypsylace. That is a lot to contend with in life. You have way too much on your plate, right now, imo. (In my opinion)

Does the doctor who prescribes your med also give you time to talk with them? Can that doctor refer you to a psychologist so you do have someone to talk with about how to take better care of yourself (psychologically?)

You simply MUST step back away from some of the responsibility of your friend ..imo..at least until the divorce is final. It's so stressful..all of it. You just have to make time to do some things for yourself, and if that includes seeing your teen daughter, then do it.

Of course you are feeling overwhelmed, because you are! Please think about other options for a little while, so you don't completely go under with the depression, ok?

You have PC to talk with now. TC
