How will being diagnosed with mental disorders affect my success in life?

Did you not realize that these diagnoses are not public knowledge? If you don't tell anyone about them, no one but your family and doctor will ever know. Ever. There are laws which absolutely forbid doctors to share ANY of your medical information with anyone at all, without your consent. (The only exception is if a court ordered the doctor to release them, with a warrant, in the case of a criminal investigation. Which isn't likely to happen to you unless you go off and kill somebody. Which you already know you're not going to do.) The only reason the doctor can talk to your parents is because you're a minor. Once you turn 18, any doctor you see can't even talk to your family without your permission. That stuff is sealed. If a doctor breathed a word to anyone, he'd lose his license in the blink of an eye. You are FINE. Universities and jobs will never know of your diagnoses. Neither will friends, or crushes, or co-workers. No one, unless YOU tell them. So just don't tell them. You'd really be surprised at how many people are walking around just fine, diagnosed with those same conditions, and plenty of others too. Just follow your doctor's advice, and you will be fine. Life isn't going to be any different now just because you know you have those conditions (you've been dealing with them this long, haven't you?). The only difference is, now that a doctor knows your problems and can treat you, things are going to get better for you. You'll see. Going to a therapist was a wise choice on your part. They are there to help you, not publicly slander you.
