What's the best safest medicine for anxiety? I don't have all symptoms of anxiety but I feel like I may benefit from meds with no side effects.

None are LT safe. Long term use of any is not good. None are certain to have no side effects. Short term can be helpful esp if combined w/ CBT therapy to learn mgmt skills. If your spread of symptoms is not too bad, it might be sufficient alone. Also, you handle life more successfully. Let a good psychotherapist evaluate you and recommend Tx options. Best!
