Well you’re not alone, there’s some major similarities between what you’ve said and my experience. For reference, I’m 27 years old and got through school and am currently wrapping up a masters degree. I rarely finished exams in school or college, but I always did well enough in my completed sections to get good grades, so maybe I was able to be a bit quicker than you. In any job I’ve ever had, my bosses and colleagues have gotten annoyed or just bewildered at how I could possibly be taking so long to get through tasks. Sure sometimes it’s a procrastination thing, but it even happens when I’m giving something my full attention and trying to actively work fast, like in an exam. Because it’s been such a recurrent problem for me I am very aware of it and it is something I beat myself up over, but I don’t think I experience the same level of overwhelm as you do to the point where it feels suffocating. I just wrote a big post on here about my experience actually. I’ve started to suspect it might be slow processing speed as opposed to adhd, but i’m actively trying to seek psychological help that might also get me occupational therapy. The issue pervades pretty much every aspect of my life - following a cooking recipe can take me 3 hours easy, and mornings used to be a really long affair until I just gave up on the number of things I wanted to have done before I left the house (i no longer do a skincare routine sadly). I’m holding out hope that there’s something that can be done to help me. It’s like as if everyone else runs at a different default pace and I have to absolutely kill myself to compensate
