Maybe try ASMR, it can induce very similar effects to touch, the personal attention and physical feelings.
There are masses of these videos on YouTube, it’s worth finding your triggers and an ASMR artist or two you like. Even if you were surrounded by people, they may not be available at 3am on a Sunday morning when you need that human contact.
Also I did this experiment with diet: Experiment Report : Sugar Loading Prior To Major Work
Tl;dr is a combination of sugars and fats before a big piece of work was really effective in increasing my magickal stamina & energy (but, obviously not sustainable for ongoing work), then coconut oil afterwards, it has some properties as “brain food” based on research from dementia patients.
Maybe adding some coconut oil into your diet will help? These stopped me crashing after doing a lot of work, and the coconut oil especially helps with sustainable energy.
So, I use that when doing heavy work over long periods, and butter as well, and if I have something big planned, I use canned condensed milk made into a syrupy drink with 3 or 4 yteasponns of white sugar (which I would normally never touch, I’m usually <75g carbs a day).
Also, make sure that the drive to keep pounding away isn’t based on an unexamined belief that if you stop, you’ll fail, that’s not good baggage to carry. I speak from experience there.
