[PostOnce]

Hey, these outsiders commenting on your situation are armchair generals. Don't fret. Everybody has different problems, but we all have problems. We get dealt different hands in life and not all of 'em can be played perfectly, you just work with the cards you're dealt.

If you can't get him in to school, then this doesn't sound like truancy, it sounds like a disability. A medical diagnosis of some mental issue would get the law off of your back and make accommodations available to you and your family, at least I assume so having lived my 30-something years in a couple of other Anglosphere countries. Here they'll give you options for home learning (but still within the public system, homeschool is a different option), for part-time public-school 2 days a week, or for other accommodations to help a needy kid.

Just wanted to say it's alright, and nothing is necessarily your fault -- I've struggled with some very similar problems to the ones you have. It's going OK now though! School is working again!
