It takes time to get comfortable with YOURSELF!
I find when you enjoy your own company it is easier to walk away if what's going on isn't right or something you want to be a part of...
I have also noticed others think you're odd. Or are uncomfortable because you are independent. With time and years I find others learn to be less needy. Also notice some realize different isn't bad just different. Others don't recognize what it is not being part of the crowd by choice.
I have learned to prize my space and peace. Few seem peaceful these days...
I recall reading Psalms in one section that spoke about "the dry places in our heart" that blew me away!
I read it go it, and was surprised the Bible addressed what I knew was there. Just knowing God knows makes those places less alone..
..they heal.
