Tears.. i Cant stop:(

My LO is 14 weeks old. She sleeps through the night, only cries when shes hungry, is super alert and smiley and here I am not wanting to get out of bed. Since her delivery I was put on antidepressants because I already had a history with depression. It helped alot and everyone around me noticed a change. I felt good and was happy go lucky. Then this past week Ive had a nagging feeling of sadness all the time. I even came home from work because I was so depressed. I read that it could be PPD rearing its ugly head at me now, and I was told sometimes even Antidepressants only make it tolerable... i hate this feeling..:*(
