<human>: Hey /r/advice. I have been debating posting here for a while and I finally decided why the hell not. I feel like my life is stuck. I am currently a senior biology student at UT Austin and I feel very inadequate around my peers, friends and housemates. Everyone around me has travelled to different places in the world, have had jobs/internships at various places and seem to be on the right track or at least more motivated than I am. I have never left the country, never had a job pertaining to biology and have never had an internship. My grades are mediocre (2.68 GPA) and I feel like I'm either not organized or not motivated enough to get my life rolling. I have fun here in Austin and I love my friends and being around them, but I feel totally inferior to most of them. I enjoy playing music, my friends do as well, they are quite talented, and I can play the piano but I can't start learning a new song/practice without losing hope immediately and quit. The same goes for working out. I have been emailing a professor about a job in his lab and he asked for a resume, references, a transcript and a future interview but I have been avoiding emailing him my transcript, resume and references, seemingly for no reason. Maybe I am afraid to move on and start new things. Every night I think about how much I should have done by now, then I think I'm too young to say that at 21, then I feel guilty again and get restless and lose sleep. I have tried adderall, ritalin and vyvance and they all tweak me out but don't really help with my ability to complete things. 
My theory: I have been told that my snoring is rather obnoxious, and that I sound like I don't get much oxygen when I sleep. Every day I wake up tired, so perhaps sleep apnea is the problem. I've also been told by my parents that I've always had very large tonsils, so maybe they are blocking my air passage when I sleep. Either way, I do not feel like I should be this lethargic and pessimistic at my age and I feel like I haven't accomplished nearly as much as I ought to have.

Can you summarize the given text in a few sentences?
<bot>: I would like to know how to be more organized and motivated since I haven't done enough in my 21 years, and I feel ill prepared for graduate school and life in general.
