By definition, insane means: in a state of mind that prevents normal perception, behavior, or social interaction; seriously mentally ill. I don’t use the term, so I looked it up before answering. In my opinion, lets look at it as “Signs you are thrown off your center”. Signs could be such as memory problems, difficulty thinking in situations where it is usually not difficult, behaving with a short temper, feeling bored or unmotivated, unable to connect to others as usual, and on and on. Signs like this do not necessarily indicate that something is terrible. Sometimes it is a sign that you need to look more closely at a situation and make a change. This is sometimes a wonderful thing to happen in life so you “wake up” make a positive change or get out of a situation that is not in your best interest. So, if you find yourself feeling “off your center”, figure out what is throwing you off, then decide what to do.
