Mental conditions originate from many sources, whether medical or emotional-physical abuse or a learning style ignored or a type of autism wrongly reacted to. Situations like these get worse and worse, spiraling around a self-smothering cocoon of crazy. Once cocooned up in the crazy tree, no one can help that person more than that person is willing.
Everyone feels the pull to climb crazy trees at times. The only thing that pulls us down from climbing crazy is love from other people. Knowing that someone on the ground loves us and calls out to us can call us back down.
