I get you. Been a little while since I went, but it was hell. Idk how much longer you’ve got left but I can absolutely promise you with certainty that in your scenario, it will 100% get better with time. One day you’ll be graduated and look back not understanding how you even got through it, but you’ll be so glad it’s over.
I worked four 10s through the week in uni, and did full time classes all day on every single day I had off. Man that sucked. Stemmed from the same issue you’re facing, and to me it was worth it to move out and struggle that way than it was to face the constant back and forth between my family and I. All I can really say, is keep it pushing and finish strong. Because it does get better, even if it feels like it never will!
Waxing? I don’t. I use a wax based lubricant for sealed chains but am I missing some ancient technique?
