I used to think it was a negative thing that I isolated and think it was a defect that I got my energy from alone time. Being social exhausts me so I take my by myself time serious nowadays. What changed things for me was coming here to SR, hearing about an author named Susan Cain who has a book out called:
"Quiet: The Power of Introverts in a World That Can't Stop Talking"
Now I accept that I am in fact an introvert, and I am not doomed to drink if I spend time alone.
She has an excellent Ted talk out there too. Here is the link.
Susan Cain: The power of introverts
I'm almost 3 months clean and I too can "feel" that this time is different. I have learned so much here, and really want it this time. I have no reservations about using this time and feel really strong.
Congrats on your 5 months!
