The thing about mental illness is, it lies to us. Imagine your daughter or grand daughter saying those things about themselves. I imagine you would tell them that is far from the truth. Though I dont know you, I believe its the same in your case. It's how you feel, but that doesnt make it true.

I hope you will one day reach the point where you see your worth. It most definitely is there. Until then, just put one foot in front of the other.
