I think some providers have there own views on the DSM. maybe you T is clouded by his own diagnosis

Does a label matter ? Yes in a way it does to think you have xyz and mentally take that lane but then you are told no would be confusing.

Be proactive and get your questions answered and if he isn’t willingly to really sit back and look at things , maybe getting another opinion or T altogether might be the best thing.

For now ? Just work on the symptoms your having trouble with.
