Sometimes you need to find which drug works best for you. What works for some,
does not
work for others. I think you will get well on the medication that suits you. You should not get too many side effects when you find the right one.
Give it a bit more time, and see how you feel. If after 2 weeks, there is no difference, go back to the doctor. You may, or may not get out of this depression, but I think anti-depressants will help.
Let us know how you are feeling now.
