Not feeling it

Recently my boyfriend and I have hit our one year and we had amazing hotel sex but lately I just haven't been in the mood and when we try I feel so grossed out. I have been under a lot of stress and depression lately so was thinking it might be that but I'm not sure. I definitely have a sex drive but nothing he does turns me on anymore. I love him so much and want to be close to him but feel so off right now. I need help!
