You're doing good.
You already know that what you're hearing is misleading, and potentially harmful.
Continue to ignore it.
Focus on your plus points and things that make you happy.
I don't know which country you live in, but I can try to look up helpline numbers for you if that'll help?
Also, if this has happened before, find the advice you've been given regarding coping strategies and implement it, if you haven't already.
