I too know how you feel. I was so bad yesterday I was sick of being me. I felt like you that it is unfair to the people I love. But today I feel some better. I am taking Lexapro after being worthless for about four months. It is really helping me. Maybe you should talk to your doc. I don't have the answers because I would not be here if I did. But these dips are temporary and we must cling to the hope of a brighter day.
