sex drive and depression

Ok, so I have a really high sex drive, I mean I always want to have sex with my boyfriend, alll the time.. but I've recently been put on a depression pill, my sex drive has decreased massively, I don't want to have sex (well my mind does but my body don't) and I'm also struggling to orgasm, can someone tell me if it's going to stay like this or how I can stop this from happening ??😓
