A tear does not signify your weakness. It signifies your strength to get up and strive again after you have hit low.
It signifies you have learnt from what happened and are again on the path to make things work. A symbol that you are not stuck.
Though low, tears make the best telescopes to future, give one the best vision and they do release the bodily tension one feels.
Don’t feel shy of your emotions. Let them flow and be your strength.
