Trust

Without trust, we have nothing. After the week I've had, it's so hard for me to trust anyone. My guard is, once again, up. I had finally gotten to a place where I started trusting people again. Well, that's shattered. How do you know when someone is trustworthy? Should I really trust someone with my heart, with my secrets, and with my life unless they prove otherwise? I am so confused right now and completely vulnerable. I want to think that there are decent people out there that have my best interest at heart but I just don't know what or who to believe anymore...
