I got that same feeling on Zoloft. I did not want to eat either I could only force myself to eat 1 grill cheese sandwich a day and was very tired and just felt terrible. I stayed on it for 2 weeks but my symptoms did not get better they got worse as each day went by so the doctor took me off of Zoloft I am not able to take any of those meds. Just keep trying and maybe those side effects will go away for you. They are side effects to those meds but with some people they go away after a few weeks
