It isn't like I don't understand your concerns and worries. I probably understand them too well. I just think that personally you have the ability to better gauge your personal well being than most people because of the fact that you actually get to the point on occasion that others don't and would be aware of the warning signs for yourself.
But if you don't trust your instincts to let you know in advance that something feels off and get help for it before it becomes an issue, then you're making the right choice.
[But then maybe a collar is a better choice in this situation. Zero on the other hand refuses to stop struggling unless he actually begins to show he signs of fatigue or restlessness that assaults him when the monster within starts to rear it's ugly head. Too many people are relying on his help right now to give in.]
