It sounds like you are saying your point was that diagnoses don't mean you can't have a life or do things and that's definitely true.
You're having a new provider who has relabeled you is a separate issue from not being defined by a diagnosis. What you wrote about being diagnosed differently now than in the past was frustrating because while you may trust your provider, sometimes they undiagnose people and it's both unwelcome and silly. To look at a child or adult who was diagnosed with ASD after years of therapies etc. because the person looks more normal now with no regard to how much effort it has taken to get or stay there and say the person never had ASD seems wrong to me, and sometimes, it happens. I think it's arrogant in that situation for a provider to think they know better than numerous people in the past. Not saying that's your situation, but it happens, and the problem is treating a person as if he or she is typical when that isn't true won't adequately meet their needs, and that's a very difficult experience to go through, because being depressed and on the spectrum and not understood is incredibly lonely and isolating and a lot of people here have been through that. I am glad for you that you are feeling hopeful, and this seems to be what you want, so your situation is different, but the message you are writing about hope and not being limited by diagnosis I don't think should be limited by relating to diagnoses. It's for anyone and everyone.
