Depression freaking sucks

So I’ve hit a rough patch in my relationship. My bf doesn’t find me sexually attractive sometimes. So we don’t have sex hardly ever and when we do, I feel like its on his terms. I feel like I get on his nerves constantly 😕. Recently we had a brutally honest talk and it sent me into a panic attack and I was just getting ready to walk out because what he said hurt me to the point where I think I’m gross . I told him I’m sorry I can’t look the way you want me too . I’ve lost 100 lbs and I have loose skin and stretch marks. I’ve lost 2 cup sizes and my ass is well just not there . I’m trying to make myself happy and work things out with him, but I just don’t feel like me anymore . I feel like my depression is coming back. I’m always tired, I’m over eating and my stomach is always in knots. I don’t know what to do, I just went through a bad break up in the first months of 2017 and I’m scared to go through another one . He seems to want to work on things and I do too, but deep down I just don’t know how to feel .
