My most painful experiences involve feelings of alienation and disconnection. So sometimes I find relief from these underlying feelings by confiding all sorts of things in people I don't know well / have reason to trust. Sharing relatively intimate things about myself leads to feeling of connection. Connection - even if illusionary, relieves the anxiety of aloneness. This, in the short or long term leads to regret because all sorts of people - some not ultimately not well/disposed towards me, know a lot of sensitive info about me. This makes me vulnerable, and evokes shame...
