Stars, you have let no one down.
OK you are feeling panicy and wobbly today - very understandable under the circumstances.
It does not detract from the fact that you are fab, strong and gutsy.
Look at what you've achieved so far. Off the top of my head:
You've given your DC care and love
You've put your anxieties to one side so you can go to meetings for your DS
You've posted on Mumsnet for help
You've spoken to Womens Aid
You've spoken to the Council
You've been to see (a sadly crap) Solicitor
You've made some brilliant lists of things to do.
You've admitted to yourself that you deserve better
You are talking and planning for the future.
Each of these things (and I'm sure I've missed loads out) on their own take guts, especially when you have your H sniping away at you constantly and eroding your self-esteem and confidence.
The fact that you are having the odd wobble and panic and sometimes don't have the strength to do these things doesn't mean that you stop being "fab, strong and gutsy". It just means that you are not superhuman - and it would be very unreasonable for anyone to expect you to be that!!
How can this be made as simple as possible for you? You don't have to jump through hoops or prove your worth to anyone (especially not the arsewipe you are married to).
Please take help that's out there - whether letting WA deal with some of this or whether taking someone to appointments with you.
There is no shame in taking help that is on offer. It does not make you less of a person - all it means is that you are reclaiming what you deserve - happiness, help, affirmation and admiration for being the amazing person you are.
Please take it easy and be kind to yourself. Our faith in you and admiration for how far you've come is not conditional.
