Worried😔

my daughter is almost 3 and I'm so bummed bcs a while back she got a really bad diaper rash before we potty trained her and after her diaper rashes healed we noticed white spots in her genital area. We didn't think nothing of it but I've done some reaserech online and think it might be vitiligo since now she has more spots. Vitiligo it's a skin discoloration disorder. I'm just so worried for my baby we made and apt with my doctor and he sent to a special so I'm worried even more. I know things could be worse but i can't Help to worry & feel sad for my baby. I know how mean ppl can be and am mortified for my baby girl. Am I jumping into conclusions or should I acept the fact that she might have it and everything will be ok. It's just breaks my heart. 💔💔
