Freedom from the constant time wasting and hassle of feeling like you "need" to update your virtual life every other second. Freedom from others having any expectations of you "adding them on Facebook". Freedom from the random messages from long lost "friends" that all of a sudden want to know everything about you and then some. There are deeper ways to "connect" with people that don't involve all of the rigmarole. What you do with this new found time and freedom is completely up to you.
Explore your interests in the real world. When you're with friends, actually "be" with your friends; not on facebook. Join a Meetup in your city. Paint, Write, Workout, Read, maybe even start a PT business. Really. The world is your Oyster. Do with it as much as you can, while you can.
All it takes is the first step forward and then the pieces will fall into place.
So the first step in removing and deleting your Facebook Permanently is to Want to Live your Life in the Real World.
And the Second step is to Contact Facebook Directly and tell them you want them to Permanently Delete your Facebook account.
And the Third step is to Take a Deep Breath and Rejoice for better days await you.
Congratulations you have successfully, Permanently Deleted Your Facebook Account!
