No sex in 4 months

My husband has always had a low sex drive. I'm the one who lost his virginity to and he was 26 when we had sex. We had sex maybe 3x a month before and now we haven't had sex in 4 months. 3 months ago he had a psychotic break. He's schizophrenic and we were having insurance issues and couldn't get his medication which caused so many problems. He ended up running away in the middle of the night and he was found by police crying in an abandoned building with no shoes on and half naked. He got taken inpatient after being missing for 4 days. He's back on his medication but since then there's been no sex at all. Our sex life is completely dead. I'm starting to feel unwanted and ugly. I want to feel desired and it's been so long since I felt sexually desirable. I love my husband but I'm starting to feel depressed now.
