and heres what youve been waiting for: advice from an 18 year old
we seem to have little in common except for recovering from some kind of depression (and being "quick-witted, smart, funny, sarcastic" and unfortunately also having approach anxiety) but i think i have something to share anyway.
1. watch kung fu panda. i know what youre thinking, but you wont regret it, its great. and the main protagonist is fat (not saying youre fat

) and throughout the plot he develops self confidence (without even losing the weight). seriously, its very very motivating.
2. you have humor? then use your flaw(s) as comedy material! instead of serious thoughts about it, imagine funny situations that involve being ridiculously overweight. my dad is your age and when hes having a good day hes often joking about his recent weight gain. there needs to be no bitterness because of it, especially since its something you can lose and are already working on doing so.
its all gonna work out, and you are too
and forget about the books (did you mean "the game"?) and spend that time and money in having fun and doing what ever the hell you want to, what did you do in happier times? if something comes to mind immediately you might be missing that now.
i sound a little pushy, sorry.
p.s. ive started out as a keyboard jockey on this site like most people, and honestly what valuable experience can you have at 18, but what i wrote in this post has worked for me so far.
