Ive been feeling really self conscious lately about my appearance, I just feel like everyone else is staring at me when I go out, Do you ever feel that way? 
sometimes i do, especially since i gained a lot of weight
Yea my heightened sense of self-awareness really makes me freak out, I often thing the feeling will never go away. 
is there anything you can do about it? is there any treatment?
Well I definitely know that it can heavily impair one's ability to perform complex actions. So I know that there is therapies for it and even medication.
