Their song moments is about suicide. Ed Sheeran wrote it, but that doesn't mean that they only sing about getting girls. (just putting that out there, I love One Direction too(: )
Hi:) First I'm here if you ever need to talk! Second I would probably talk to my dad first and see what he says. If you feel like somethings fishy and thats not true..then I would tell my sister and then go to my mom with her by my side.
At dinner, when your whole family is there, start talking about it. (: Trust me, it'll be loads better than just telling your sister, and this whole thing will be cleared up in no time.
