newmummy, how old is your son? I have to say, that i would personally (because i hate shopping) find the shopping centre a bad place to be when i am going through a bad time. I have PND too. Its shit, i have good days, but i was sat where you were yesterday - but the thought of my little girl visiting my grave has kept me alive.
Are there any groups you can find out about? To be honest, when you first start going, they are a bit shit - but you do eventually make friends. I slowly made friends with another mum who suffers with depression - we never talk about it, but we "know" if you know what i mean, if we say we were feeling shit etc, we know that its best to leave alone etc. Its so hard.
Do you have a homestart in your area? I go to a play group run by homestart, its great, its just a playgroup rather than a support group and DD loves it, and i just get to sit and chat, or sit and brood and glower in the corner if im having a weird day. But no one takes any notice, its like, LEM has got PMT, best leave her alone today.
Enough about me, please realise that you are a very important person, your son needs you and loves you. You talk about the way your DH is, but you dont go into detail, so its difficult to decide if its the depression talking or if he is behaving like an arse, or both. It is very difficult for the partners, i have given my DP such a shit time, but there have also been times when he has been a twunt too.
What medication are you on, how long have you been taking them? Tell me about this support group you mention? I find it helps to know that my friend "know" about my illness, and friends who have been there are truly the only ones who can understand.
Tell us more about you honey....we all want to help (sorry, its way past wine o clock in the LEM house even though i shouldnt be drinking on the ADs)
