I am seeking your real world experiences with Anxiety Medications?

My 15 yr old son is not do well and we are facing the prospect of putting him on Anxiety Meds. My research shows there are many out there. What little I do know is they seem to be a crap shoot with lots of potential side effects and how long he might be on these? I am looking for your experience (hopefully good) with these meds.

PM me if you prefer to remain private.
