My love, when you've taken the steps you need to start healing yourself from this, you will know that the only person there to help you is within you.
That tiny little being has been neglected, squashed and ignored for só long. But she's there! In time, given space to express herself, she will grow and learn.
Then you'll know what love is! :)
You were bullied at school because of bad self esteem.
You felt that being alone was a bad thing and fell into a bad relationship after come out of another less than ideal one.
Self esteem.
The fact that you ended it is good, but sadly your abuser knew he only had a small window, and upped his game.
You caved, because of the lack of feeling that you deserved any better.
The one thing that all this has in common, is the person I have not spoken about yet. Your mother.
She taught you, that little girl, that you didn't matter, were unlovable, and worthless.
The bullies, the abusers/weirdos all just hang off that.
Your mother is dead. I know you say you miss her, but really you miss the mother she never was. You need to really look at this relationship, and see where all that worthlessness came from.
I'm sorry, it's a hellish thing to have to look at when the person's already gone. There will be anger, hatred even, but they are only feelings. They need to be expressed. You have an absolute right to express them, you can't heal any of this until you do.
Have you looked at Daughters of the Narcissistic? Could she have fallen into this category?
Try also the stately Homes threads here and open up about your upbringing.
There are many of us that have almost carbon copy lives, and by taking the time to get to know the little girl within us, and nurture her to being a fully fledged adult, we recover and heal.
