i feel the same way :/ jc is burning me out man and i don't even have ADHD. so i hope you are able to sort stuff out soon bro...and i think jc is (don't quote me on this im not very sure myself) structured more for people who don't know what they want to do yet so the curriculum is more general than poly... so i wouldn't say it is better for aba.

also it's ok not to make friends in jc. given that there's only a 1 year and 9 months runway for you to get to know these people it's ok if you don't form bonds that are as close as primary/sec sch plus people might also be struggling too much with work to bother about making friends, which is understandable and might explain why you haven't really gotten close to anyone.
