What helps apart from medication?

I've just got my GP to refer me to PsyUK through right to choose. I'm aware I'm now in for a long wait now before I can find out if meds help. Is there anything else I (M48) could be attempting in the meantime to possibly help with procrastination, motivation, timekeeping or social skills? I know the old "exercise, diet and sleep more " advice would likely have a positive outcome if only I could only convince myself to stick to any of that for long enough. Did anyone here find anything except their prescription that helped make day to day life easier? I'm trying to navigate a possible career change that could occur way before any hope of my assessment happening. It feels quite an insurmountable hurdle right now.
