[Ethereal]

I have terrible self esteem, but I've found that when I do things I enjoy and I'm good at, I feel better.

You could write down one good thing about every time about you feel badly about yourself.

It might be helpful if you come up with a positive mantra and write down in heaps of places and say it over again. :D

something along the lines of " I am beautiful, and do not deserve negative thoughts." or, whatever you think would be helpful.
