My personal experience and opinion:
I was prescribed antidepressants (think it was the same as yours) when I was going through a divorce. Yes, it does take a few weeks to take effect, if at all it does. I say this because, it did nothing for me . I am not a doctor but this is my theory: if your depression is due to 'circumstances', medication won't help, simply because the 'circumstance' is still there. Here self help is the only solution. Mind over matter,
However, if your depression is clinical, these medications will certainly help......give it a few weeks...if it's still not helping, talk to your Doctor. All the best bikergran xx
