There's a type of burnout lately that I've noticed is fairly unique to INFJ's and ENFJ's but with INFJ's it's got it's own unique flavor. ENFJ's can go out and get lots of support from their friends and be relatively alright. INFJ's have to do one of the hardest things in the world to prevent their burnouts. They have to say 'no' to the pain of other people.
Now, what do I mean by burn out? Well, an INFJ begins helping people with the best of intentions and digging out little pieces of their psyche, rebuilding them emotionally when things have gone poorly and comforting the hurts of the moment. It's one important way that many INFJ's validate themselves and often it becomes a veritable lifelong purpose to see other people healed.
If an INFJ is not in good control of themselves and their lives, they begin to seek more and more validation through this healing process and spend more and more time on it until their empathy begins to atrophy and they collapse. The collapse generally means they can take back some control in their lives. It's an excuse to drive away people for long enough to get some space inside their own minds.
Once the burnout happens it generally takes the form of a fairly dramatic collapse and change in behavior. Some people go mute temporarily. Others just hermit in and close themselves off from people for days or weeks. Once the burn-out is done, the INFJ generally re-emerges a happier and friendlier person...but if the stress isn't off it begins again.
I've been in this cycle before and lemme tell ya, it sucks.
What I want to know is...well, aside the obvious unpleasantness of it...have you noticed long term changes that come out of sliding into this cycle? What are the benefits? What have been your experiences?
