Alleycat, you've gotten some pretty good advice here. Just in case you have trouble coming up with something positive about yourself, which many of us do at one time or another, here is something to help you start.
"Today I will stop looking at myself through the distorting dark glasses of self-criticism. Instead of focusing only on my defects, I will look at myself in the light and accept myself for the wonderfully complex being that I am. And just maybe, this is how others will see me, too."
"Today I will say no to the broken records of fear from the past. I will say yes to the innocent curiosity within me; yes to the path of growth and discovery and joy."
Repeat these in the morning when you wake up and repeat them when you feel yourself start to pity yourself. You could even write them out and read them to yourself whenever.
