I just wanted to come back and post that after a long road of anxiety and severe depression I started Lexapro and continued on this for 4.5 months with many ups and downs (horrific downs) as well as terrible headaches at least 15/30 days a month. I switched to Zoloft a month ago and am happy to report I feel great and anxiety/depression free and have not had a headache in a while. I never thought I'd be able to write this post since I surly thought I'd be in a psych hospital long term it was that bad. It still amazes me where your brain can take you-what a scary, terrifying place that is. Thanks for all your support on this site, it truly helped me get through some hard times.
