allgonebellyup, i have posted on your threads in the past, and you have posted on mine and really really helped me.
WTF is going on sweetheart? Please please talk to someone, get out of the house, do something.
I have to say this: Just imagine if you HAD succeded, your children would have found you - do you really want that? Of course you don't. I know you are desperately trying to get help here, but like the others have said, we can support you with cyber hugs and listen to all of your problems but you need to see a doctor. Please do this, and do it today - out of hours, A=E anywhere. You dont have to turn up at A+E with cut wrist to get there help, just go there and tell them what you have just done.
I know of several people who have commited suicide, i promise you, it is about as shit as it gets for those left behind. My cousin found his dad like this when he was seven - he is 37 now, but one very damaged young man
I'm sorry if this doesnt sound very sympathetic, but you need help, not sympathy just now. Of course i am sympathetic, but this is NOT the way - you are a wonderful mummy to your children. The children who are at their dads just now, but will be coming home later today or tomorrow and will want there mum to be there for a cuddle.
I know its hard to see through the mist, but please, it wont always be like this i promise you.
