Congratulations on the best score possible - or at least, a 94 is the top mark at my uni. Sounds to me like you might compartmentalise your life somewhat so college/college/uni occupies a speck in your head and home occupies another - and never do they meet. If studying on site helps you, go with it. Why fight it?

With regards to how will you cope if you take on more... don't do that just now. Your skills and stamina will grow. Your ability to study in different environments will improve. But for now, just enjoy thriving as you've figured out what works for you in the here and now.

I left school with my highest grade being an E in English (U.K. GCSE) I just couldn't handle school. I'm now on my second Masters. It gets easier the more you do it. I'm now addicted to studying!!!! 🤐
