I think it could be both. What u are describing sounds exactly like me before I was diagnosed with both anxiety and ADD. The worrying and wanting it to be amazing sounds like anxiety. But the lack of focus, the getting overhelmed and ending up not doing it at all sounds like ADD. I would talk to your t about it and maybe she can do a few tests. If not to diagnose u, then to rule it out. Because I know that after I was diagnosed, I took an ADD med for the 1st time and it was amazing to finally be able to focus and get something done for once. It was rly an amazing experience. Also ADD and anxiety are often comorbid.
