I feel terrible. I was on prozac for years. Me and my nurse decided to try something else because it didn't seem to be working well. This is my 3rd day on lexapro. My head hurts. A lot. Like near my eye. And I just feel really agitated and upset. I don't know how to explain how I feel. I feel bad. I just had to get that out there. I'm seeing my therapist on Monday.
