You are not 'going on' poshsingle, from what I recall, you don't have it very easy, and whatever the reasons for having DD and knowing that the choice was perhaps made retrospectively for the wrong reasons, they were important at the time and you made that decision based on where you were then.
I am 16 months down the line from my DC's father walking out on me, and I though by now I would be OK. But I am not. I like you am a mess.
I am getting help because like you I feel that there is something badly wrong with me.
Accepting that this is going to be a long journey with some twists and turns and bumpy bits helps a little because it takes the pressure off to be OKer than I am.
Can you source some help? I am paying for my own counselling, I was cross at first as I thought in a lot of instances other people had messed me up so why was I paying in so many ways, but it is actually a gift to myself.
Can you do something like that?
It is hard, but accepting that changes might be small and slow, but that you can make them, can also empower you a little.
However bad I feel about where I am now, if I look back to those 16 months ago, myself and my DC's have actually come quite a way forward.
Sometimes I wish their Dad would just evaporate because it is taking a very long time to stop enabling him to mess with my head. And it is all the more easier when I am low or vulnerable.
Take care poshsingle and try to be kind to yourself, even in some small ways.
