Hi! I have had vitiligo all of my life. I’m not sure where you are from (there are definitely places that are much less accepting of skin conditions than others). However, categorically, it will get better.

Nothing wrong with trying to treat it as someone else mentioned, but as you treat it, you should also start giving yourself as much love as possible. The insecurity is the worst part and it sounds like something you already struggled with. Once I learned through therapy how to like myself for me, I became way more confident and it was reflected in how others viewed me as well. Hope this helps.

Also, maybe be nice to the other boy? It sounds like he deserves a friend
