Ama.... as being a former fellow lexapro taker... i COMPLETELY understand how you feel. You need to definately talk with your doctor. When I was on it, I didn't care about life or what was going on. I'm quite the snuggling/touchy feely person, and I didn't want to hold hands with my boyfriend. (So if you have a partner, talk with them and tell them how you feel on it and that you are trying to fix it.
Maybe you need to change the pill overall. Please keep my posted.... I'm here for you.
