You are the only person who can decide whether you should take medication your entire life. If you feel that you need it, you may likely need it.
With that said, both my sons have stopped stimulant and ADHD medication after taking it for years because they wanted to and we have not seen a decrease in functioning. It is quite possible.
Hopefully, you have people who support you in your decisions no matter what they are.
You’ll make the right decision. Trust yourself.
