Hi @Sirgalahad
Welcome to the Forums. I hope you don't mind, but I have moved your post and made it a new discussion so you can get more responses.
It can always throw us when we feel like we know what track we're on and what diagnosis we have, but then it come into question. Unfortunately, many people get multiple diagnosis - sometimes they agree with them, sometimes not.
What is important is your quality of life. If you are living the life you want and not being hindered, this is a great sign. For some, when they are unable to function and feel like their current treatment isnt working for them, they will seek out another opinion.
Just to clarify, how do you work with your supervisor? Is this in an academic setting (ie: people who are doing their Masters or PhD have 'supervisors) or is this a supervisor at your work?
