Shia, whooooo hooooooooooo............good for you. Yes I believe you could be feeling a little anxious from the med so hold on and tough it through if you can.
All the AD's may do that to get on them. I am very proud of you. You deserve a standing ovation. It took courage to get past your fears.
Hugs to you my friend
Sounds like you are doing fabulously..how smart to start on a low dose and work up..that means milder side effects. I've not been on Lexapro, but know of many people who have had success with it. Congrats on getting started! Let us know how you go with everything okay? Here to listen my friend.
