Hi Billy,
Truthfully, I lead a "sheltered" life by choice. I'm not a hermit by any means, but I pick and choose when I do go out in public. I base it on necessity as well as how I'm feeling personally. If I'm not up to my best for whatever reason and I absolutely have to go out into public to take care of business or shop or run errands, I take on the Walter skit approach (Jeff Dunham) - "Welcome to Wal-Mart, get your S^^^ and get out!". At times it feels more like a recon mission. But another thing I try to do when going out in public is choose times that places will be less crowded. I absolutely refuse to go out during the early evening when people are getting out of work, etc. I can't handle it and have literally left stores in the past wanting to kill because of all the negativity, exhaustion and short tempers around me. Thus, it's not a healthy thing for me to do.
Now, please don't take it as I am secluded by any means. I have friends that come over, and I go to their homes as well. But I feel everyone! One of the methods I practice daily is H.A.L.T. It literally means - Hungry, Angry, Lonely and Tired. I evaluate how I am on all those aspects physically, emotionally, mentally and spiritually. If I'm lacking in something, I deal with it. I have also attended events, and other activities where there are larger crowds and have had wonderful experiences. But, with anything, I do it all in moderation.
When it comes to investigations with other groups or when I am contacted for a reading on a home, etc. I go through a lengthy process to ensure that I am totally rested and in a good frame of mind before I attend. Basically, I feel like if I am not at my best for each day (and that varies for a "best" physically), then I am no good to anything else. But keep in mind that because I may not be doing the greatest physically at points does not pull me down on a mental, emotional and spiritual a-okay. In short, just because I may not physically feel good doesn't mean I'm not happy.
Practicing positiveness is also a big thing in my life. Looking at the glass half full instead of empty.
The turning off of things or tuning it out comes with practice. It gets easier as time goes on... but the most important thing to remember is your health and well being comes before anything else.
