Trustworthy?

I was reading a friends blog on trust and i didn't know wether i am trustworthy or not.

I would hope that if anybody wanted to talk to me about anything they would just go ahead and say it, rather than bottling it up and if anybody needed somebody to talk to, they would look in my direction but it actually struck me that they don't. My 'best firend' only trusts me to a minor degree but no more than he would anybody else he knows. This concerned me. If somebody is not able to confide in you, are you able to confide in them?

I do not trust people with the things that concern me the most. I probably should but i just don't. I have realised that i would not talk to anybody even if i was super desperate. I would keep it locked up inside me and hope it would go away. I realise that this is stupid but i am just not a trusting person. I do not even trust my bestest buddies, which is terrible.
