Sometimes things happen that we don't know how to handle. This is a part of life. You handle it the best you can in the moment, you ponder what else could be done later, and you move forward with the lessons you've learned. Nobody knows how to handle life at all times. Nobody has all the information they need at all times. We all have connection to the source of the best information we could have, but it can sometimes be hard to tune in at the precise moment you need it. With practice, it gets easier.
Trust that every action that comes from your best self is enough. Trust that any help you offer is enough. Trust that you are enough. Trust that you being you in this world is the best thing for all of us.
