I am surprised that getting over a divorce or break up would require a pharmaceutical solution. Not belittling the traumatic effects, but there is a big difference between being depressed and being unhappy. It seems we have got lumbered with the word "depression" when in fact it should more properly be called suppression, as in reduced seratonin production making you unhappy chemically and physically. this is different fundamentally to depression, where emotionally you feel low.
Suppression is unhealthy, depression as I described it, is healthy and necessary, I would suggest, as a part of the healing process. So it isnt that great, but if you can smile and laugh now again and dont feel like a ton weight is on your shoulders and your memory isnt failing you and you dont look at the ground but still look people in the eye and you can still do a job you would expect to do in your sleep, then I would talk, not pop pills.
I suffered a head injury and this brought on a severe depression as in severe suppression and I would not wish it on my worst enemy. Also I would not wish my enemies the same trials and tribulations as I experienced when doctors tried to find a medication that worked on me. At one stage I was about to pour petrol over myself, instead I ran away. I was thankfully picked up and driven to hospital by a friend and as a result the big wig psychiatric bods were called in to sort me out where my GP was failing miserably. I ended up on a tiny dose of amytritylin which is an old fashioned so-say weak and insignificant drug but it was not part of the prozac family which had made me so paranoid. So be afraid of drugs and if there is the slightest feeling that you can just pull yourself together after a n emotional upset like a break-up, please, do it.
If you cant pull yourself together despite your best efforts, be very questioning of your doc, and make sure you have good friends who know about the treatment, because they will notice you freaking out or changing well before you do.
