I have diagnosed adhd (since I was a child) and something I struggled with, which may be relevant to you, is that it can be really easy to tell yourself or believe you have a limited capacity to focus and later in the day you just run out. The idea that you can’t start doing a hobby because you don’t have the capacity to focus on something is untrue a lot of the time, and it’s noticeable in a situation where if you do really mentally taxing fulfilling hard work, sometimes you feel much more capable of doing those hobbies, because the same “focus” for one isn’t exactly the same as the other.

Not saying you’re wrong for feeling that way, just sharing a way of thinking that helped me out a lot
