Myself, my psychologist, my friend Jonesy, and I guess I trust my family to...stick by me. I don't really tell them anything, though. They tend to overreact, or give me unwanted advice. But I could trust them if I needed to.
I trust different people with different things. I trust myself with everything, except maybe sharp objects, because you can't really hide things from yourself. I trust my psychologist to listen to what I have to say, and not tell anyone. I trust Jonesy to always be tactlessly blunt, and tell me when I'm being an idiot. I trust my family to love me unconditionally. So it really depends. I can't say I trust any one person with absolutely everything, though.
