My mom always asks me whats wrong. But when I tell her she always minimizes it and goes on about how shes worse off.

I have BPD and am currently really deep into a depressive episode and my mom got frustrated with me because I didn't want to talk to her about it and started making fun of it and blaming me for making her worry and she does this all the time.

I would move out but I'm 17 and don't really have funds to do so and id be worried about her getting rid of my cat (as she often threatens to do)

I dont know what other options I have to deal with her and the situation but I dont think I can take being around her for much longer.
