Others are giving you very good non-medical suggestions, and I hope you will try one or more of them. In addition, I think it is important that you tell this to the doctor who prescribed your antidepressents. Print out what you wrote here, or write down how you feel, and put a date on it. When you talk to your doctor, read them the words and tell them how you felt today, even if you don't still that way on the day you are talking to the Dr.
Sometimes, what's needed is to change your dosage by 1/4 of a pill or so, but please do not change it up or down without talking your Dr first. Brain meds are tricky.
