I was on 5 mg of Lexapro for about 1 month, and I was feeling good for about 2 1/2 weeks and then out of nowhere I had a panic attack and I feel like all my anxiety has came back. I just feel hopeless, alone, I feel very spaced out and unrealistic. Now my doctor has put me on 10 mg of Lexapro, it has been 4 days and I still have yet to feel any better or any side effects besides insomnia and nausea. I just feel like I'll be like this forever and I'm tired of suffering.
