I'm a hermit. Would I be in better emotional condition if I had friends? That's a difficult answer, since I don't really want friends. I'm happy being alone. I do have a husband and my 2 grown children and I might get lonely if I didn't have them. But I am not motivated to be social. I know how to be social, but just don't prefer it.
I think ChickenLady, that if you are happy not being very social, then you should try to accept it in you. The question for you (and me), is "Does our un-socialness contribute to a life that might be more difficult because we are not getting what might be good support from others?" I personally just can't push myself to be social. In fact, I dig my heels into the ground if I'm forced.
I think there's probably many people out there who aren't gregarious, and that's okay. Are you feeling like something is missing because you're not totally sociable all the time?
