Sadly, I agree with everyone else that has been replying to your post.

Your mother has issues that she hasn't dealt with otherwise, she wouldn't be nice one minute & attacking you the next. When we are feeling depression in the first place, being around that type of personality isn't healthy. You need to stay away from her as much as possible while she is in that kind of mood.....& definitely not depending on her for your support. Who knows, maybe that depression she says she has just recovered from.....is a depression that she HASN'T REALLY recovered from as it sounds like she has some pretty serious stuff going on inside of herself & may actually be driving your depression into being much worse.

I know my depression was bad living around my husband for so long.....when I left him, my depression has really dimished.....still have anxiety that I am dealing with, but being away from a person who was driving my depression was the best thing I ever did.

If your dad can be a good support to you, then I would look to him for your support.....but also having friends outside of the family is very very important especially since your mother is reacting the way she is.

Wishing you a peaceful life soon & the ability to keep away from any harmful personalities.
