I woke up from the surgery 7 days ago and have suffered from 24/7 anxiety, over thinking, worry, bad thoughts, heart racing all day. I went to the dr after day 3 and he prescribed 10mg lexapro with .5 zanex 3 times a day until the Lexapro kicks in. I am not on day 3 and still having all day panic and anxiety. Is this normal? I feel like there is not end in sight. I'm 37 and extremely healthy. Never experienced anything like this. I have not been able to work or do anything with my child. Do I need to give it more time??
