Hi MoodyMrs!
I'm sorry for all that you have been through and continue to go through!
I can semi relate to what you are going through. I have a rocky relationship with my parents and I have effectively been emotionally abandoned by my mother. While she is still present in our lives, she is never there when she is needed in any practical or emotional way and doesn't really fulfil a mother role. I won't go into all the messy details because this is your thread.
I think the hardest thing is letting go of the fantasy propagated by society of what a mother is. I was very struck by your comment mothers aren't supposed to do this because I remember thinking similar things myself.
Society tells us that mothers are these paragons of virtue with endless supplies of inexhaustible of unconditional love for their children. For a lot of people this is probably true.
So it's really hard for people like us, who have dysfunctional mothers, to realise that this is a myth and that our mothers do not have unconditional love for us and in some cases might not love us at all.
The myth is so strong that you keep tripping yourself up with it. I was blind for years to the abuses I received from my Mother because I kept telling myself 'She's my Mother, Mothers don't put themselves first' or 'she's my Mother, she couldn't really have abandoned me when I was ill and in pain in the hospital'. I completely ignored the evidence of my own eyes because of the Myth, even though other people witnessed these incidents.
The problem with the Myth is that you reflect it back on to yourself. Mothers are supposed to love us unconditionally, so if they don't there must be something wrong with me, we tell ourselves.
That isn't true, there are no unloveable unworthy children, just crap parents!
Why not give the counselling a shot, if you don't find it works for you then you can just give it up. I wish I could do it but I can't afford it!
I do think that there is a degree of wisdom in just getting on with things too. I'm learning to live well and not let me crap relationship with my parents effect me too much. I try to look after myself and my family and push the negative elements aside.
I hope you feel better soon.
