electra, you MUST give yourself a break here. I have recently started on citalopram, an SSRI. NAB3 - prozac is prob the most well known. I am on it for severe anxiety and depression. I was going under i really was, now i am coping. I'm not better, but im getting to a stage where i am back in control. My advice, based on my experience is take them. They work. Then, push your doctor until he gets you signed up for some counselling, im still waiting for mine although i have had an initial assesment. It is important, i think that you dont just rely on the pills, otherwise when you stop taking them, the problems will still be there. But then if it is PND, maybe once your hormones have sorted themselves out you can get back to normal. A friend of mine did exactly that, took prozac for 3 months, been absolutely fine since, had to do this following the birth of both of her children.
I am sorry to hear about your dad, you dont say, ive only read the op, what for. It is possible of course that his ADs have in the past been poorly managed too, resulting in an addiction, but i dont know the situation. Just to say that SSRIs are not addictive, not physically so, of course there are some people who will rely on them, i think if you tried to take mine away youd need a very big stick just now, but i dont intend to be taking them long term, i am hoping i will know when i no longer need them.
I am sorry that things are shit for you just now. You deserve to feel better and your children deserve for you to feel better too. Take the pills, make sure your doctor sets up some help and monitors you. My doctor has been brilliant, she is a mum too and i feel she really understands, im lucky about that i guess.
