Tag poems with feelings

When I look in the mirror, I hate what I see.
I’ve gotten so used to seeing the overweight me.
I start a new diet and it ends up on a shelf,
Like I’m trying to prevent seeing my skinnier self.

I need to get it under control, or I could die
So why is it I lack the motivation to even try?
I see all the problems, and what I’m doing wrong
So why is it I can’t change the song?
