a year after my surgery I was diagnosed with depression. I started taking Zoloft and I saw a difference in 3 weeks! I was having body aches, fatigue, loss of interest in everyday normal things. I had mood swings!!! and a short temper... I started talking to my doctor about it and she had me come in and see her and she gave me a questionaire and I scored an 18... normal is 2 or 3... severe depression is what she said it was... If you feel like you are barely keeping your head above water like I did, talk to your doctor!!! there is help!
