Again, Donna, if this site was having a contest for beautiful girls who have zero self-esteem whatsoever, you'd take the cake.
Every single time I hear you use the word "ugly" to describe yourself, every single time you say you see a guy in the mirror, my reaction is "OMG, is this girl freaking blind?" I just don't see how it's even possible for you to feel that way. I really don't.
Trust me, your problem is NOT external. It's internal. If you could see yourself in the same way that we see you, you'd never have self-esteem issues again. Trust me.
And it's REALLY scary to read things like "nobody wants me around." That to me sounds like you're not only having self-esteem issues, but actually burying yourself in a self-defeating cycle of depressive thoughts that are seriously in danger of consuming you. PLEASE, do not let that happen! Don't let that little voice inside tell you that you're all alone and that nobody cares about you. We do care. So please, don't tell yourself that nobody does.
