Complete change

[HeartIsAching]

So, this is me in a nutshell:
-never had a girlfriend
-I have bad grades
-my hairline is receding(although I want to be a shaved hair/bald bearded guy, I always like to have my hairline visible enough)
-I'm a little overweight(slight gut and love handles)
-I can't concentrate when I'm doing something
-I feel unattractive
-I don't hang out a lot, because I have few friends and few people who enjoy my company

This is my life since I reached puberty, my parents told me that it was just a phase and it would be over soon, but does this "phase" go on for this long?
Point is: I don't want to be myself anymore, I want to change, COMPLETELY. The only thing from my former self I want to keep is my character(since you can't change it). I want to change everything about me!!!

So, what are you going to do about it?
