I want, at this moment, to stay away from Second Life.
I’ve never had a serious addiction and so I don’t know what it’s like to quit, but I have this “weight lifted off my shoulders” feeling ever since July. I feel free. I’m creating things, I’m going outside. I still have lots of RL and stress, but mostly, I just don’t want to log in.

Dear Misteltoe, you – and everyone else – should always do what you feel is best for your own well-being. SecondLife is not, and will never be, a life-sentence. We are in that world if we wish to be there and if we no longer wish to be there we should walk away without remorse or regrets.
All I ask of those who leave SecondLife is two things.
1) That they inform those with whom they have had a close friendship with of their decision and say farewell, either like you in a post on your blog or through a notecard. It is absolutely f*cking horrible not to know what has happened when a close friend suddenly stops logging in.
2) That they do not badmouth those that have decided to continue in SecondLife.
I am happy that you are feeling much better and that you feel free. Take care, be safe and best wishes!
Hugs,
Bock
Excellent points, both. I will try to keep both firmly in mind.
