I Want to Be Positive About Life

I'm not all negative. I will have a few stories that will sound harsh and extremely bitter, but that is just the truth, not trying to be negative. Anyway, I get the feeling people who have a positive outlook on life probably will live longer. Negativity is ok to a degree, then it becomes excessive, redundant and toxic. Sometimes I don't want to face people in stores like walmart and king soopers because of my anxiety and panic disorder, but I relax, gently go in and do my business, and then I notice, everyone else is just doing their business too. When I feel there are 10 fingers pointing at me, there is usually in reality just one.
