We are long distance and broke up during finals, the day after her major stat exam at 2am. Around this time, she was extremely stressed, busy, tired and depressed. For almost a month she'd been feeling "numb" and like everything was "numbed out". She'd apologise a lot for being irritable and unpleasant. Before this, she said she couldn't feel love for me because she couldn't feel anything and felt sad because of it (I guess she could feel emotions sometimes). She has a history of depression, as do I. We were both bedridden for 3 months because of depression and have both taken SSRIs.
Since the breakup she has been acting somewhat erratic and strange, but is even more distant than she was while we were together. I want to be there for her as a friend but every time we talk she just gets angrier. She hasn't blocked me on Facebook Messenger but made a new twitter account, blocked me after a few days despite not interacting at all, and then made several "joke" depressive tweets (hating herself, having low motivation/joy, changing her mind a lot(?), being unhappy). She jokes about her problems as a coping mechanism, aside from that she just doesn't talk about them. I tried telling her to get help for her depression but she refused.
It has been just over 3 weeks and we talked maybe 5 times, 4 of those times I initiated the conversation. Last we talked, she unblocked me on twitter despite being mad and deleted all her sad tweets (will likely use her private account now).
When we were together, she said her state of mind changes every few months and she was in a very good state of mind when I met her. She said she used to be "genuinely crazy" because she was very depressed and acting dumb because of it. Before the breakup she also said she'd been in a weird/bad mood for a while and didn't have much to say. When I was very depressed and anxious, she was supportive of me, and I want to be there for her but she won't let me. We bickered a lot over pointless things (my fault, anxiety) leading up to the breakup.
I don't think I want her back but I want to reconcile things. I just don't know what to do, I'm worried about her. I don't want to talk for at least a month at the moment because she treats me poorly, but I want to be there for her. I'm really confused because this whole scenario is so strange.
