Need sex advice...life advice....help

Hello, I'm 20 years old, been with my boyfriend for 2 years now... So the past few months I just haven't been wanting to have sex.. My sex drive has just died basically, I don't feel comfortable during sex and for some reason I just don't feel pleasure anymore.. I don't really understand why, lately iv been really depressed and snappy, bitchy, and I don't fully understand why.. I have no energy to do anything, I never feel happy anymore, I'm getting so tired of it, I feel like iv lost myself, and its effecting my relationship, I don't know what to do, iv tried antidepressants but they make me feel numb or don't work, I hate it, I don't think councling would be right for me, I don't see how talking to a stranger works honestly.... Its been like this for years and I just can't take it anymore....
