Because you were ‘treated for stress’ so young makes me suspicious about those in charge; your care givers and doctors.

All children experience stresses. Sure, some of us go through extremely stressful situations.

Is it possible someone thought, instead of allowing you to feel stress and learn how to handle stress, that you needed to be extremely medicated?

I suggest you discuss this with a good therapist. What you described has triggered Red Flag warnings in a lot of us here, for sure.
