Crying has always considered to be a contemptible thing.
Even your first response encountering a crying person would be 'don't cry'. I wonder why is that...
But crying is healthy. It's letting out the bottled up emotions buried deep inside of you. It's loosening yourself up. It's painful. It's relaxing. It'll leave you breathless, panting. But, it's a good thing.
So, loosen yourself up. Don't blink back those tears, don't lock them up again. Let them out, let your stress lighten up, let your sorrows lessen, let that mental turmoil ease, let your feelings express and let your soul cleanse with every teardrop that falls.
Don't hold back. Let 'em fall.
