I was DX with GAD/ Panic Disorder 90 days go. Meds are 15 mg of Lexapro (escitalopram) daily with. 50 mg of Ativan. I am not much better. Should I insist on new meds?

Not necessarily. GAD can be challenging to treat and some times medicines is not the right therapy for everyone; you may wish to consider simultaneous behavioral therapy and/or yoga/meditation. Getting to the source of your anxiety and treating that may be more meaningful and may even allow you to get off meds. You ought to explore behavioral psychotherapy as you are young and being on Ativan (lorazepam) is not really optimal.
