I love food so much I think I'd have a LOT of difficulty only eating once a day

Oh, it's not so bad after the first few days. Sometimes I shrink my stomach down by doing this when I don't have a lot of money. The amount of food we eat vs. what we need are startlingly different. I enjoy food immensely, but I also like to exert a certain amount of control over certain things in my life.

I know you said that these lines were not exact:

    You never do end up with the girl
    you know you're meant
    to end up with, so you find someone
    sort of similar, less 
    convicted hair... 

but why break the line, "you know you're meant/"? It seems to me that you could get more play out of:

  You never do end up with the girl
  you know you're meant to end
  up with, so you find someone
  sort of similar, less
  convicted hair . . . 

I don't know, that break just seemed a bit awkward to me, but maybe it works better in the context of the full poem.

I've never thought about writing about myself as a peripheral character. I think part of it is that I don't know how I appear to other people, or at least I haven't thought about it much except in the context of their immediate reactions to me in a social situation. That could be something to explore though.

As for your edit, 1=I, no? :)
