I had a meeting with the local mental health team recently, and she asked me how I was feeling, and I genuinely had no idea. I said 'I honestly don't know', I felt flat but not empty, neither up nor down, but not in the middle either. She looked at me like I'd just told her I was a walrus made of cheese.
Since my diagnosis I've begun to realise that often I have no idea what my mood is, and that I've mistakenly thought I'm fine when I'm actually far from it. I guess that's the issue with mental health, as a professional you're having to ask someone with a brain disorder to tell you what they feel. You're not guaranteed to get a correct answer. I know I held back on stuff when I was diagnosed because I didn't want to sound like I was crazy, or trying to be crazy. Still ended up with the diagnosis I expected.
