You're experiencing "Post-Kingdom-Hall Syndrome" (PKHS) in which symptoms include strange feelings of normality that leave you feeling uneasy because you're expecting something bad will happen. Withdrawal symptoms will see you idealizing your JW friends and grieving for them, wrongly believing they are irreplaceable.
At an intellectual level, you know you've made the most intelligent and informed choice (by staying away) but at an emotional level, the FOG (Fear, obligation and Guilt) kicks in big time. You will be susceptible to spiritual blackmail.
PKHS is also manifested by fear-based urges such as the need to avoid causing others concern, to be careful about how you navigate your way through endless possibilities (What will I do if the elders call? How will I come across if I see them when I am out in public going about my legitimate business, etc).
One day you will look back on PKHS and realize it does not last forever and that you have moved on to a better, more fulfilling life. Best, steve
