Husband making me feel bad

Just had our first baby 4 months ago. I had a lot of complications healing my c section and then got an iud at 9 weeks pp. I’ve had very bad postpartum depression on top of being bipolar as well. I finally got new medication yesterday. Problem is since I was cleared I have barely wanted to have sex and my husband does all the time.

Idk how many times I’m gonna have to repeat myself. I just don’t want to, I guess it’s just not important to me anymore. One of the medications I was put on I’ve been on before and it makes me completely unable to orgasm so that’s probably not going to help this situation. I can’t force myself to be in the mood and I don’t know what else to say to him to stop making me feel guilty about it. Him annoying me everyday makes me not want to even more
