We sit in our rooms and think. We wonder, "What would have happened if I had just done this? Would things be better if I had only acted differently then?" We get caged up in our regret because its too hard for us to move on; we're too wrapped up in things that have already happened and that we cant change. Maybe it just causes us inmeasurable stress and makes life 1000 times more difficult, but overthinking and overanalizing is what we do.
