depression is destroying my marriage

I've struggled with depression most of my life. Sometimes I'm doing well, other times I'm not. Right now I'm not, I'm unhappy and moody all the time, I don't have any reason to be upset, it's not situational. I have no sex drive, I haven't had sex with my husband in two months, he's very frustrated, I just don't feel like it and last time I did it I couldn't get into it. As a result he didn't enjoy it either. I just feel lost, I don't want to go back on medication, I hate the way it makes me feel. We are also ttc, which isn't going to happen since we don't have sex and I honestly think it would probably be a bad idea anyway with the way I'm feeling these days. I do see a psychologist about once a month, but it's not helping lately. Any advice?
