It's good to challenge a diagnosis at first to beat the label and a probable misdiagnosis and to get a second opinion. By doing so, you might save yourself years of psychiatric flubbery and not receive any valid help.

If you do get a different second opinion, you can always go two for three and hope that the third opinion matches one of the first 2. That's what I would do instead of me having to pick between two opinions.

Once you have satisfied your brains concerns, acceptance will happen as you get more comfortable with the process. Good luck!
