Okay first off your not too young for surgery, where the hell did you get that idea? ive read a story on this site about a 12 year old who got it, im 17 and i just got it done, 365 days older then you and somehow im qualified as 'old enough' for it?? Secondly if its pure fat and not gland then yea work out and quit complaining, things in life dont just come free becasue you want them too. However if there is genuinely gland in there then go and see a plastic surgeon, because working out wont lose that for you. And about your 'underdevelopedness' its what you make yourself, yea you cant help some of the changes you may want (deeper voice, facial hair, muscle development due to testostorne etc) but if you learn to carry yourself properly, with an air of confidence, and dont let people push you around becasue you feel sorry for yourself, you wont have any problems. Stop saying you hate life and stop whining about not taking your shirt of in front of people, even people who never have gynecomastia usually keep there damn shirts on, what your doing is putting all your emotional baggage into your chest. Get the surgery and get it over with soon so you can fix that depression and have the rest of your life (especially teenage years) without it. Oh and by the way, lose the weight, its not hard work all it involves is a lifestyle change, i dropped from around 230ish lbs pre summer (6 foot 2) to 180 now with substantial muscle development, this caused almost all the fat around my Gyne to go away and made it look much better while i was waiting for surgery, if you want to know how to get in shape and lose weight (its a science, it does not equal eat less exercise more) pm me and ill explain nutrition and exercise to you.
