I’m going thru the same thing, currently trying to get my AA, I can’t be medicated for my adhd since it’ll make my mania real bad… I’m honestly not doing too well either at the moment, but some things that have helped me is making sure I’m “in the moment” before I start a task, either by meditating or by slowly building up the mindset that I’m about to do the task by doing small little preparation things (like if I’m having trouble trying to do an assignment, I’ll make getting my computer/supplies out in general my main priority, and even though it may seem like a small step, it really makes things seem less intimidating). Set small goals for yourself and slowly make those goals bigger as you get comfortable with the smaller ones. But we all have times where we feel like nothing is working (how I feel lately, honestly) and I think a key thing is to be patient and forgiving with yourself as you try to find something that works. Remember what you have accomplished already and tell yourself even though you’ve hit a bump in the road, you’re trying your best, you’ve come so far already.
