I hear you Ang. It is hard. And it never stops.
It amazes me how some people have no idea that my DS has ASD, SPD and (probably) ADHD. But that's because at home and out and about we control everything - where we go, what we do, how we do things and all the prep prep prep for anything. When I am with him I can pre-empt almost all his troubles and modify the situation as and when I can. So mostly he copes and is happy. But the incredible amount of effort from his parents to get him to that point is staggering!
I'm actually OK getting through all the day to day stuff, the planning, the meltdowns, the behaviour - exhausted and stressed (and sometimes to my shame I do get cross with DS :(), but manage OK. It's those things that are out of my control that give me such anxiety. DS's problems at school, the constant letters and meetings and telephone calls and never being able to take my eye off the ball, and not being able to sort it all out for my DS so that he has no anxieties of his own :(, and the future, I worry about his future - from tomorrow to next week to when he is a teenager, an adult...
I have (had) a really high pressure stressful job, that demanded my attention 25 hours of the day. Trying to cope with that, and my DS, and then my own sudden ill health, caused me more stress and anxiety than I could cope with. One thing I personally found really helpful was "mindfulness". It takes some practice and I used a combination of books, cd's and classes. But it really helps when I am anxious and stressed. It helps stop the worrying about what might happen and lets you focus on the here and now and all the positives.
Autumnsmum - that has made me smile, Bless your DD2. Will school be OK with that?
