I've been friends with "A" for about 5 years now and she's always struggled with deep depression. I also struggle with depression and anxiety. For awhile she was doing better and feeling happier, but lately it seems like she's hitting rock bottom again. I'm trying to help her as much as I can, but I also need to make sure I'm not getting overwhelmed. Last time I talked to her, she seemed angry and fed up with life and she was even snapping at me. I keep sending her nice texts but she's barely responding. How do you help a friend through depression when you are struggling yourself? What sort of boundaries should I have? I feel like it's my sole responsibility to help her because she confides in me about everything....
