Yes, a lot of people go through a kind of 'self denial' period. It's self stigma, which is the most damaging kind of stigma. Try not to overthink it. You were diagnosed with a disorder, but it makes you no less awesome and it doesn't take away from your worth. Everything's okay, and.now that you know you have it, you can work towards managing it.
