I'm sorry that happened to you. I wish people actually offered help instead of just torturing others and making their situation worse. I hate how non-understanding relatives/friends can be. I guess I'll never understand people who have never felt suicidal before.
Try to act normal even if it's hard and they will get bored of it quickly and forget it. Think about all the terrible news; tsunamis, explosions, earthquakes, plane crashes, etc. People will be really shocked for a few days/weeks/months and then often forget it ever happened. (or at least that's how it is in this country)
