Thanks guys, it's been some time now ( I wish I could actually remember how long, but over a year ), but I don't really talk about it to anyone. I have, as Caine says, put it away without too much thought. I'm not sure if that's just drawing out the process, or if that's just how I deal with things.
My dad had reached out to me before he passed, but I had other problems in my life that means I couldn't be there for him. They were things way out of my control, and I don't even really know if I could have made a difference, but I suppose it's typical to question yourself when something like this happens. Since it happened after the other problems, well, there wasn't really any room left in my life for more disaster so I kind-of ignored it and moved on.
After the funeral I just sort of sat quietly, didn't eat much, and slowly drank myself unconscious. It wasn't my proudest moment.
@FaeMinx I've been watching the Alien movies again recently, watched Aliens yesterday in fact. Legendary film! I didn't know it was John Hurt in the original film until Alt-J's song "The Gospel of John Hurt"... yup random weird hipster music contains Alien factoids...
On a positive note, I've moved on, moved away, and moved jobs to something much more fulfilling where I get the chance to help and educate people on a 1:1 basis and really explore my potential as a professional "tinkering with random electronic shit" guy. I'm managing to haul my ass back down south on a semi regular basis to see my daughter, too.
Which leads me to a song:
