I feel like a nobody

I always feel like I have the worst of the worst. My skin is all scarred up, I have a big gap, my hair is short and coarse, and I have knock knees. I feel like no matter how cute I try to look I never actually look pretty. No one ever tell me how pretty I am. I’m super shy so I’m awkward around other people and I always think other people are talking about me when they’re around me. I’m 25 and I’ve never had a job for more than 2 weeks, I’ve been in college for years but always drop my classes. I feel so behind because I’m just now working on my prerequisites while everybody is working on their second degree. I don’t work, I’m super skinny, sometimes I don’t eat. I just want to do better in my life. I know the exact type of woman I want to be, I just don’t know what route to take to get there. I was never taught how to be confident, or self esteem so I don’t know. Plus I have a child and I want to be so much better for him.
