I'm pretty sure there's no sexuality that justifies constant low-level harassment.

Don't let a friend make you feel publicly uncomfortable indefinitely just because they're probably a lesbian.

Nothing good comes of reading other people's emails.

So many people choose silence after the immediate wake of a death out of fear of saying something out of turn or "bringing up bad memories" that bereaved people often feel forgotten.

I hate to get gender essentialist, but I'm starting to think that a lot of married men have some sort of heterosexually induced dentistry aversion.

You have a wonderful opportunity here to not care about something that doesn’t matter to you. Please don’t miss out on it.

As you feel increasingly comfortable around your friends, I think it's more than fine to share the basic details of your heroin addiction with them. If they seem receptive, you can feel free to talk about it in further detail; if they seem judgmental or uncomfortable, you can move on to other topics.
