My point is, don't make this out to be something it's not, like you will be in lock down, you won't. Looking at this from a different perspective can help, what you have done so far is not working, time for a new way to view this. Your mind is working overtime to make you believe you are off to work on the chain gang and will be forced to do things you don't want to do and that is just not true. It's just not.
