As far as I know, the chief concern is when you are applying for high-intensity jobs. As part of governmental background checks, they always ask you--and your friends and family--if you have sought psychiatric or psychological care, and you are obligated to be honest. What they make of your disclosures depends, I guess.

There is no requirement that you be free of mental diseases or disorders to practice as a therapist. Of course, you have a moral obligation to your clients to be healthy so that you can help them most effectively, but being in therapy really works toward that end, don't you think?

The biggest concern I would have is whether this diagnosis will become what insurance terms "a pre-existing condition." Sometimes, when you get new insurance, the company declines to cover you for a pre-existing condition, which would mean they wouldn't pay for therapy. For example, I have asthma, and every time I get a new insurance company, I have to disclose this (they've always covered me). It's not practical, though, to delay or stop treatment based on a worry that a company might do this at some unknown point in the future.

What you and your therapist might do is agree on another diagnosis that better describes your problems but that might be general enough for you to avoid worrying about future stigma or insurance conflicts.
