I Have Trust Issues Okay?

People ask me 'what's wrong?' everytime I look sad. And when I say I don't know, don't look at me like you think I'm faking. I either don't want to tell you, there's more than one reason, or I probably really don't know. Sometimes I'm just sad. And if you don't understand that, I'll probably give you a random reason so you'll just leave me alone. Sometimes I'm sad because of the memories and thoughts that run through my brain, and usually no one can understand them, so sorry if that makes me keep to myself. But hey, if I do tell you what's up, it means I trust you and I love you, and I'm grateful that you're here for me. That's all I have to say for now.
