I am so sorry. Will things improve soon?
I don't know why you need to work so much but clearly you're trying to stay on top of things.

Is it possible that a money makeover would help you at all? I always find, when I'm at the bottom, that organization is what keeps me going (simply being in control of something helps). A financial makeover would give you that sense of control. Someone would tell you what you have, what you can spend, how much of each bill you need to pay of, what you should consolidate, etc.
Not only would you feel as if you're doing the best you can, but it would be organized and, therefore, manageable.
Feeling out of control is a big part of depression. Especially if it's about money.....

Just a thought and please feel free to talk to me...

ETA...I apologize for coming across as....however. I tend to be quite **** retentive and the urge to organize sometime spills over into my convo's
