Mine has just gone back to school (first year middle, 11yo) after 2 years HE.
And it wasn't for the 7.50-1.37 (with one ten minute break) hours or the avalanche of homework.
He had three sports clubs, over 15 hours a week of youth club and going to play with his mates all the time while we were HEing, but he still missed the social aspect of school and asked to go back.(about ten minutes after I triple checked he wanted to continue with HE and ordered an expensive load of books)
Kids are all different and some will always yearn for that "in the thick of it" enviroment of school regardless of what style of HE their parents offer.
2 weeks is still early days so that might not the case for him, but don't beat yourself up if HE and him turn out not to be the perfect fit.
How about asking him to give his all, to catch up as much as possible in English and Maths (with your help) over the next couple of months with a view to returning to school in a better place ?
If the objective is motivating to him (do the work, get back to school) that is more positive than "if HE fails I can get back to where I want to be". Possibly the focus on improvement rather than missing school will give him time to adjust and appreciate HE, but if not, at least the time out will have gone some way to improving his educational foundation before he does go back, which might have a knock on effect back at school.
I feel for you love, you must feel awfully between a rock and a hard place.
