My dad got diagnosed with a tumor in his brain during November of last year. It happened out of nowhere and I got to watch my dad slowly lose all semblance of humanity, one day he'd be fine and the next he wouldn't be able to move or stand up. Things got worse and eventually my dad lost the ability to speak normally/construct any sort of coherent sentence. Meanwhile I was so busy with college (exams, projects etc) that I barely had the time to go visit him at all whenever he was at the hospital or spend time with him. Around the last week of January I was almost done with college for a while but his situation got even worse, he fell into a coma and the doctors deemed his situation hopeless, so they decided not to try and feed him anymore as it would just extend his suffering. When I came home just before my week of holidays was about to start, I received the news he had died (he was 59 years old). A month has passed since and I'm still incredibly busy with college. Meanwhile my mother is slowly losing her sanity over all the paper work and administration that needs to be done because of his passing. Things just haven't really been the same at home, I often catch myself doing things like set the dinner table for four people instead of three etc.
tl;dr dad died of cancer last month, staying focused in college is a pain
