feeling bad...

So I have depression and anxiety it started cause of work and I left there rather quickly and thought things would get better... with the meds they started to I have always a horny women and have to have sex at least 9 times a week. My husband is the same. We have been trying for a baby which has gotten me down. My sleeping patterns were bad before the meds but this last week I have slept properly in 5 days and I feel rather naff... today I broke down crying and I'm finding harder to do things like drive and cook clean and read. But all this scared me in comparison to last night my partner was supper horny and started kiss him and I refused him and told him I really don't want it! This morning I apologised and he was fine he just asked me to look after myself while he was at work and it doesn't matter but I can see it on his face. What can I do?
