Huge body image issues

I just can’t feel good in my skin. It’s too unclear, too many acne scars, too many stretch marks and I don’t like my face shape and thin oily hair or my skin colour or that I wear glasses. I try to tell myself that the main thing is that my body works, but I just hate looking at myself in the mirror and not look the way I want to look like. I want to change something and look good, but no hair cut will suit me and I’d need bleach for colouring my hair, which will damage my already thing hair… and money for new outfits and new makeup. I just don’t know what to do because I have tried to appreciate my looks but I can’t. I just don’t think I’m attractive and I feel like I need to have my first date or relationship with a boy for validation :/
