Pokemon alot of weird things happening now :P
first of all how could you say they are your friends and they mock on you, do you really care about someone mocking you??? (1 weird).
2nd do you really shame from your picture?? i don't know how you life with your self then , try to positive at yourself.
many people do surgery to thier body just because they shame from thier body i wish you are not one of them , because everyone has a miss on his body,mind,and everything...
try to be brave.
last thing if the picture about you when you were young like 1years old with something funny don't shame because all of your friends did that too ^^
