Thank you for your comments chris1234. Good for you for responding so quickly to the problem and avoiding what could have been a really bad situation. That took courage.
I sometimes talk about homeschooling or unschooling so he did ask if he could do that. We're at the end of the school year so we'll have the summer for everyone to mature and become more confident. If things are bad in the fall then we'll need to look into coping skills, counselling and maybe an alternative school method for the year.
Thanks for your help. This forum is such a great resource!
