adelicate...
I hope I am not intruding here, but I wanted to share something with you.
I have not been through what you have, but did experience emotional abuse from my mother. Lack of any expression of love being the hardest thing to deal with, until she told me at 16, that she never wanted me & tried to self abort. So, I do know how that little girl in you feels, regarding the abandonment.
I had a termination earlier this year that I had some counselling for & it brought back many many feelings from my childhood. I had/have some reoccurring problems with that abandonment still, so still find myself crying when I get a trigger. I have realised that one reason (not the sole one, I suffer terribly in pregnancy - Pre-eclampsia etc.) for having the termination was because I was scared I couldn't love a 3rd child, because I was a third child & I was unwanted & unloved.
I have to say that I find solace in my children. My daughter, 6, sees me upset & cuddles me. And while it doesn't replace the cuddles I needed/wanted as a child, it does help me to know that she loves me unconditionally. I never tell why I am upset, just tell her I am feeling poorly etc./having a bad day but feeling her arms around me is soothing & helps a little. I think it is because I never felt that unconditional love from my mother, but I feel it from her.
I haven't seen you mention how old your children are, but could you not try, just once, to see if that works for you? I am not advocating you tell them everything, just seek solace in them & see where that leads you.
I feel like a little girl in my little girls arms, but she is SUCH a comfort, more so than dh sometimes. I think it is that lost mother/daughter bond for me.
I wish you luck, adelicate. I hope you are in a better place soon.
