That's really hard! My parents are both dead now, but I came out to them years before they died. My dad was fine about it - didn't quite know how to talk about it, but he was from that generation of englishmen that didn't know how to talk about anything emotional. I was always close to him, and if anything coming out helped that. My mum never quite accepted it, but she was OK about it - that was always the difficult relationship for me, and knowing i was gay certainly didn't make it any more difficult. And my stepmother simply asks when I'm going to find the right man to settle down with!
I've never come out about the necro interest to anyone offline, but then to me it's something that's only online anyway - I've got no serious interest in doing anything with a dead guy for real.
Not sure if it was Roadkill or Meatpie that siad about friends not sticking round. I've had a bit of that - the last few years have been hard for money and health, and I've noticed that quite a few casual friends have disappeared. But the real friends stick around, and help out when they can - they're not all fairweather friends. And I try to do the same for them.
