Mmm, looks like some treatment seems necessary. Of course must be disconcerting - especially when so young. Also I think our medical conditions can affect how we are, but are not who we are.
There are women who have thinning hair and invest in wigs. These wigs look like real hair and are gorgeous. They aren’t anything like an ugly wig for an old lady...but beautiful. No one should feel ugly and terrible about themselves.
If you don’t look at life more positively then I don’t know what to tell you. I’ve seen some unattractive people to be funny, positive, loving,caring, compassionate, and selfless.You need to stop focusing so much on yourself and focus on helping others. You will feel better for it. @IAmNothing
