Wife has depression/mood disorder

I love my wife and we get along great but she's had issues with depression and mood disorders in the past, which she took anti depressants for, and sometimes those issues pop up and cause problems in our relationship. For the last few months she's been doing acupuncture and using herbal medication to deal with her issues, it's been working pretty well but it's taking time and she often has pretty sever mood swings. I always try my best to understand this and make her feel good but lately it's become more and more draining. It's come to the point now that if she gets upset about something I did she will get VERY upset and I will have to try to calm her down by repeatedly apologizing even if I made a harmless mistake. On the other hand, if I have a problem with something she did/said and bring it up, then she will complain about being a burden for me and become very upset/depressed until I have to somehow apologize again to smooth the situation. When my wife is healthy she recognizes that these are problems with her mood and that she doesn't mean to act this way. I love her I know the type of person she is, so that's why I can put up with as much as I have but I just feel physically and emotionally exhausted. Sometimes I will have to deal with her mood swing in the middle of the night which is very hard for me since I don't sleep enough as it is. Sometimes I even question my own mental health because I don't know what I'm going to deal with on any given day and it makes me uneasy as well. I guess I'm making this thread to hear from people who've been in similar situations, but I'm also doing it because I have nobody to talk to about this and I feel like I have to vent some of this frustration. Thanks for reading!
