I'm one of those people. I have bipolar and paranoia which can make me seem very cold sometimes. When depressed or paranoid I avoid eye contact with my neighbors and when on a more upswing we have long conversations and get each other. We live in a questionable neighborhood so I think we both get worried sometimes and they have been very understanding towards the personal issues my family has faced other the years. They have 2 special needs children too and do we just get each other. The people who know me accept that I go through hard times and withdrawal. They allow me space and are there when I come out of the fog. I'm very grateful for them. (((Hugs)))
