I have to agree with
>>3 &
>>4 about the journal. I have one and it helps to write all your troubles down or past events.
To be honest, I don't trust anyone except myself. I don't want you taking down the path of not trusting anyone. Maybe you should talk to that person so they'll know it's a sign that you trust them enough to tell them about your issues. But it IS your choice whether you want to talk to them or not.
