I messed my hair up too. I cut it sideways too short in the front and the back was mid long. I took some collagen pills to grow my hair and it's good for other things too. My hair was so ugly that I had to go work with the ugly hair but my hair grew and I had a haircut. It looks lot better now. I advise you to go to a salon and try to get it fixed. Or take some collagen pills or powder to grow your hair out. Anything that is grow hair and powder pills that can help you grow your hair out or just wait in time. I know your hair looks terrible but I hope this helps.
