When I look at myself or see a picture of myself I just want to break down and cry, I absolutely hate the way i look. Why?

You sound like you don't like the way you look,this could be because of a range of things, but it sounds somewhat like body dystrophic disorder, which causes you to see your body differently to how it really is. Have you spoken to anyone else about this? It seems like you could feel quite distressed because of this, maybe read the 7cups guide on body image. You are not alone in what you are experiencing and many people have been through this, so try not to alienate yourself because of these feelings. There are group chats here on certain topics if you'd like to discuss it there.
