Hello and welcome Lisa.
I saw your post on the Friday night thread, so am just popping my head round the door.
Sorry to hear you are stuggling with depression at the moment. Many of us have been there and can relate to what you are going through though, so stick around and keep posting, because there's so much knowledge and support here that it really can make a big difference.
As Indigo said, saying he has ASD, but not a learning disability means that he doesn't have a low IQ, but may have problems with some aspects of learning due to the way his autism presents, eg working in a group, abstract thinking, creative writing. Its good news as lots of things can be done to support him and help him overcome these barriers.
I have 3 dcs, ds1 is 9 and has ASD, ds2 is 7 and dd is 2 years 7 months.
(Just had a thought, you might not be used to the acronyms - ds is dearest/darling son, dd is dearest/darling daughter. If you look across where it says Talk, just under where it says Mumsnet Talk at the top of the page, you can click on Acronyms and it brings up a list of the most commonly used ones.)
I totally relate to your feeling of being trapped at home at the moment, not least of all because, not only is it half term, but ds1 is ill (he's always dying when he's mildly poorly, but fails to tell anyone when he's properly/seriously ill, so is usually really bad by the time we find out) and we are we are all stuck in the house with him. He's in a vile mood and keeping everyone awake for pretty much the whole night to boot!
I can't wait for next Monday to come as, hopefully, he'll be back at school and is actually going straight to his friend's house for tea afterwards and then onto something the church has organised as a sort of anti-halloween event, so I'll get a proper break. I am really nervous about him going, but at the same time desperate for the break.
