lexapro

i have suffered from anxiety for about half a year now, and im on lexapro which seems to be helping the depression i guess, i dont know it just kind of makes me feel nothing, but at the same time i still have anxiety along with it.im on 15mg now and have been on it 4 weeks.i started at 5mg to 10mg to 15mg cuz i feel like the anxiety wont go away. Should i try 20mg?? Or am i just not giving it time to work? ANY suggestions would be lovely.

I tried it and did not like it at all, I had weird nightmares and weird thoughts I stopped it maybe you should try lorazapam its not so hard core but works when and only when you need to take it for anxious times.
