Ideas?

Last summer, I was at a camp and one day I was really upset. My friends kept knocking on my door but I didn’t answer because I didn’t want to speak with them. After about 10 minutes, the counselor came knocking and I opened the door. To sum things up about the 6 hours after that, they thought I was attempting to kill myself. It was 6 hours of interviews, crying and honestly, a lot of people thought I had died. I told them people had misinterpreted the things I wrote in my notebook, the things I said and this one event. They believed me. My sister was staying close to the camp and so before the heads called my parents I wanted to tell my sister. The next day, she came to see me and we discussed the event. She talked to the counselors to see what they had to say and everything seemed alright. She told me, before she left, that if anything happened to me she wouldn’t know what to do. I looked at her face and I knew she was serious. This happened about 8 months ago. I’ve talked directly of this event to a few people at the camp, my sister, my parents, and my really good friend. What I didn’t tell any of these people is that when I was alone in that room, I was attempting suicide. It was too bad the counselor had knocked. I’ve been thinking about this event and I don’t know what to even do or say. I guess my question for you all is, should I tell my sister the truth? I’m not even considering telling my parents, but I’m very close with my sister. Should I tell her? I’d like to hear what you guys think.
