VA Medical Coverage Questions

I just recently got rated 100% (yippee!), so I just got a few questions.

So, I know the VA will for sure cover service-related conditions, but I have no service-related mental health conditions but I want to be seen by a therapist just for my own reasons to improve on myself. Will the VA cover that? or will I have to pay for it myself?

Also, if I see a psychiatrist for my ADHD, will the VA cover that and medication as well?
