Thanks, Stevejavson
But let's say one day I start believing all that: that I'm just as good as anyone else, that I deserve to be treated with respect and I deserve to be loved. I'll still not be getting any respect and I'll still repulse people and I'll still have no one to love me. How will I manage to explain that to myself? I would be just disappointed over and over again every time someone rejects me or doesn't like me (which happens a lot). It's probably better to leave things as they are and spare myself the pain of constantly asking myself why does everybody avoid me.
I think some of us are just unfit for this world and we should accept it. What's the point of having a high self esteem for someone like me?
