I have GAD and I was on Lexapro 5MG for about 7 weeks and on the 3rd on 5MG I had a panic attack and started feeling bad again. So my doctor moved me up to 10MG and so far it was been 2 weeks and still having problems with my thoughts mainly just depersonalization, insomnia, and constant worry that this horrible anxiety will not pass or go away? Should I give it a longer time? Or should I increase? I still have yet to try 15MG or 20MG. Take it mind that I'm only 16 and have been suffering from GAD since I was 12 and just started on medication this year. Please help.
