your biggest worry right now should be your education and finding a quality career if you do not choose to go to college.
let me tell you something. everyone on here has gone through some type of problems at some point.. some of us have had divorces, family deaths, accidents, money problems.. life has its ups and downs so just hang in there and keep eating and exercising the right way and you will always have that to lean on.
also looking good and feeling good is crucial for your self confidence. there is no better feeling then walking into a room and having people look at you and say "wow that dude is jacked" rather then them saying "wow look at that fatty who just walked in"
this site is awesome and you are gonna learn a lot from these boards, its a major asset
so keep up the good work and keep your head high !!
