I'm in a shitty position, and I don't know how to cope. I'm sure as hell not going to my parents, and I cut off my blue-pill friends, and the few friends I have left are busy with semester tests and finals, so I don't want to bother them. TLDR at bottom

My grandmother has been rather erratic, paranoid, and irritable for the 6 months (although, very likely longer). She recently (or so it seems, she claims it's been years) started hallucinating voices. She initiated two divorces (moving back in after a few weeks both times, after talking with my Uncle, and then myself) because she thought my grandfather had several prostitutes in the attic. He and I installed a staircase so he could go up with her and show her. There was nobody there, and never has been, because there's no floor. it's entirely covered with insulation, which hasn't been touched in years. My mother, who is very religious, was convinced it was sexual demons brought on their home because she assumed my grandfather used pornography.
My father didn't do anything because he works a lot and is a pushover with my mother. I spent a few nights with them, and it became very obvious to me she had dementia (which runs in her siblings). She had me up 20+ times throughout the night to check the attic and my grandfather's bed for women. I watched/listened to her pace the house, turning lights on and off, yelling at the ceiling.

I brought this up to my mother a few times, and she ranted and yelled for about an hour each time (she spends 10+hours a day watching Joel Osteen or similar networks, and reminds me of a cult member) in the preacher syntax (losing a few words per sentence, speaking with a passionate, booming voice, not giving much or any context when starting a sentence).

My grandmother has moved back in with us because she hears voices the most up at her house. She and my Mom think they're in the house. Last night, she didn't recognize my Dad and thought he was trying to kidnap her. My Mom finally believes me, but I think I should be working through whatever emotions this is causing me, rather than ignoring them and focusing on lifting/reading/gaming(women)/eating a shitload/sleeping (my schedule). I can't get the thought "Today is the most lucid I'll ever see my grandmother. From here on out, she'll be sedated or delusional more and more every day" out of my head, and I have nobody I'm willing to confide my problems in.

TLDR: How do men work through a significant loss without suppressing their emotions?

EDIT: I'm curious as to why someone would downvote this. Is it off-topic? Did I offend someone in some way? If you don't need this answer, or think it's poorly written, why not just move on to another post?
