Whats wrong with me? Help me please..?

I catch myself crying almost every single night. I go on social media like & its filled with these gorgeous curvy girls. I brought up how i was a pear shape to my mom and she laughed and said i was a stick. The only one to tell me im beautiful is my boyfriend. I'm just a stick with an ugly face. My *** is flat and full of cellulite, i have no breasts what so ever and my nose is huge. My eyes look like they're always tired and i have the worst under eyes. Even when i wear makeup im still ugly. The only time i feel "beautiful" is when im making love with my boyfriend. I've picked up on a pattern, my boyfriend is very faithful and doesnt look at any women really. But every time we hangout sex has to be involved..i say no but he says please just five minutes and so i let him, but once he drops me off i don't hear from him unless i hit him up first. He then replies slow because he's always playing video games..when i call him i i tell him that i feel a certain way about how im being used and he just says he loves me and he cries over me and how im perfect. But i just told him how insecure i am and he said he wanted to talk when he got home, and i just said whatever and started crying on the phone and hung up. It's been ten minutes wouldn't someone who cares for you call? I just really hate my body and self i hate my ugly face. Ugh im 19, i come from a poor family and i cant go to college because i cant afford it. Life sucks and i really just want to die
