I'm 20 and I've been having anxiety since I was 11. I was on Lexapro and went off and was doing pretty good for a couple of months now I think I have it again. I have visited the ER seven times I had a CT scan, three bloodwork, x-rays,everything normal.Im having back of head pain and pressure,muscle spasms,shaky,stomach aches, nausea,dizzy, so many different symptoms I can't keep track. It's driving me crazy because all i do is sit home and googled my symptoms. I think I have a brain tumor or some fatal illness and that I feel like I'm going to die. oh my family thinks it's anxiety because it's been happening to me for so long back when I was 14 I did the same thing and went to the hospital 6 times and called the ambulance. and I ended up getting hospitalized in an inpatient facility where they got my anxiety under control and I was fine. I can't sleep and it just seems like it's getting worse in the back of my mind I think it's in anxiety but then another part of my mind thinks it's a illness. I started back up on the Lexapro 10 mg hoping that will work for me. i'm just scared because of the symptoms feel so real to me and the hurt and it's just hard to think that this could really be anxiety.
