Not a expert with this.. But as far as I am aware any meds which treat depression or anything like it you need to take for a few weeks for you to feel the full affect.

Hope you feel better soon

For most anti-depressants it take on avg. 4-6 weeks.
Just give it some time, how long has you been on your anti-depressant(s).
What did the doctor give you?

I strongly dont believe in medicines but my mom was on medications and all it did was make her feel more depressed and very suicidle, now she is off them and doing much better, just be sure of what you are doing! Dont take my words for granted!

i have been on anti depressants for just over a week now.and they dont work straight away,so just hang in there.you will be alright just give it time,see i am still suicidal.have tried before.but no success and am thinking of it while i am writing this,just hang in there and wait it out i know that is what i am doing..you will be fine

all the best
