well... if thats how you feel maybe reflect a bit and do something about it?
set yourself some goals and if you achieve them you might feel more positive about yourself.
I would not say you were not good looking!
I think you may be overweight which can be dealt with by making a few lifestyle changes.
I reckon if you lost some weight your face would thin down too and you would be physically an attractive guy.
Ghat will get you nowhere unless you are a lovely guy with that.
For me if you are a nice guy, then tha is what counts
