The Proverbial Teeter Totter

I am alone a majority of the time which is okay, in my opinion, for someone that is an introvert. I was alone in a public place with many people tonight and it was all I could do to make it through the hour. Now that I am in my safe place I can unwind and process my day. Alone. It is okay to be alone if I have a healthy balance but I am wondering if I am teetering on the side of isolation. I need to get out more.

Maybe I am lonely. Is that what happens when you isolate yourself to the point of being unhealthy? At what point does alone turn into lonely and why is it that I can be around people and still feel lonely? My guess is that I had been hanging around the wrong person. I have to make better choices and make sure I choose to be around people that encourage a healthy balance not isolation.
I thrive in one-on-one environments. When I go into group settings the anxiety I feel over powers my thoughts and that's when I start feeling like I need to be alone. Then I start to isolate myself and the loneliness starts to develop.
When I am around certain people I feel safe and I am fulfilled yet others tear me down to my core. I need to focus more on a healthy balance so I can be centered between the two sides of the proverbial teeter-totter of alone and lonely. ~Renee
