I'm a math/physics student and my uni went on a student strike which has lasted close to four months now, I have no issues with this but I've turned into a useless slob and feel unmotivated to do anything other than smoke, coom and play vidya due to the lack of personal interest to keep doing math.

I do find proofs interesting but it doesn't help that I've developed a sort of mental fog or "lazyness" that makes me turn to look the other way when the voice in the back of my head gives me a niche theorem I could try proving or disproving because I disregard it as too complex to tackle in my current state. This in turn has left me dull to the point that I have lost my mental "spark", at least for the time being.
I need to get back on my feet, get my shit together and catch up with definitions I have forgotten and reactivate the machine before uni fucks me over without a warning, I've already tried tyding up my room and doing a bit of cleaning around the house several times but it's no use, I just go back to bed and resume my slothlike behaviour.
