Most Helpful Guy
don't get anorexic pls it would be a pity.
don't think about your looks anon I've seen plenty ugly people in happy relationships. it's more about your outer presence like you could seem to make people around you feel out of place and uncomfortable. this issue can be worked on I am an example to that myself.
when you see a guy you like think of the possibility that he would be interested in you too instead of that he wouldn't. it will be easier for you to smile on him and make you seem more approcheable.
also don't get too hung up in bad toughts, I do it a lot and have controlled it for a while it can be sensed by people around you and it makes them less comfortable.
stay naive no matter how much you learned from past experiences it will stabilize your presence
