Here goes - Rachel - relax, You are fine - this may or may not feel true. You are a loving mother, even if you feel incapable of this right now. Actually - that last, although not a nice feeling is ok in the larger scale. It's actually good to accept and listen to your non-lovingness, it won't go until you do. The world will be what it is despite you.
Rachel - your father very probably had ASD. His are the most important mental foundations that you have built yours on. If you are feeling highly stressed, it is most likely you have gone into default, scared mode, and these are the patterns you are using to try and solve whatever is going on. It won't. Dad was globally compassionate, but as an ASD person (which you certainly have many traits of, although for you the jury is out), he also feared it and was constantly trying to fix it. So are you Rachel. You grew these foundations as a response to your father trying to support your mum through bi-polar. There were decisions made that adults could and you couldn't. Trying to control it all by thinking that you are responsible for your mum's bi-polar simply by being born and then punishing yourself for every failure (how dare you fail when you have the gift of life and have ruined someone else's?) and every success (how dare you succeed at anything when you've ruined someone else life, you deserve nothing) - well it doesn't work.
My intensity of self hatred is really quite something. It kind of explains why I'm too afraid to succeed, fail and often quite ambivalent about getting out of bed. But - it's also ok. I just need to know it's there, remind myself of it's root causes and move on. Last night I was full of the worst thoughts, had been crying in desperation in the playground as I'd been angry at D and found her ASD traits completely annoying. Ian was really cross at me, and I was cross as we'd been away where we'd had full support by staying with family and it was so blissful that it was the intense fear of coming home that triggered it for me. Deborah has been getting really challenging recently, pinching and drawing blood every day for over a fortnight has been particularly hard. Coming home was hard as she's stopped on holiday when we all relaxed and I didn't want to be so stressed I started her again.
But on the upside - we now have a specialist SALT visiting once a month who will help D communicate with us and vice versa. She's particularly keen to work with D's anxieties. Thanks to the ed psych pushing, we will also have the local pre school teacher counsellor visiting fortnightly, and I've arranged for a worker from the local children's centre to come fortnightly to encourage play skill - both kids will benefit. I'm also talking to the gp soon to see how they can help and I'm hoping to get a Home Start person soon too. And we have an OT appt in September, plus there are ways to access things to start now, and the SALT will be sending me communication stuff to use at home, so since 31st March this year (when we got the appt) - well I've been busy.
As for the rest - just remember, breathe out, let go and walk on. Be Rachel.
