Good to hear that you do that already. Are you speaking of apathy when you speak of numbness or not giving a crap? and by negative do you mean depressive feelings or destructive? Both are viewed as undesirable I suppose. You're worried that youll do irreparable damage in that state, is that what you're getting at? Yea, I can see how it is a state one would not want to fall into, but it is what it is. Those feelings are there for a reason so you just need to keep probing to find the underlying reasons for those uncontrollable emotions, and to work from there. It takes time and persistence to move through.
