Distract Yourself Into Happiness
Sometimes it can be helpful to have a way to distract yourself away from overthinking with positive, happy, and healthy alternatives. Finding a hobby or an activity that you can see yourself doing and having fun with will seriously change the way you think for the better.
Things like dancing, meditation, exercise, knitting, drawing, learning an instrument, and painting can distance you from the issues enough the shut down the overanalysis you’ve been giving your thoughts. Overanalyzing never helps and the more distance you give those thoughts the happier you’ll be.
