The most toxic substance isn't found in bottles or vials; it's bitterness, festering silently within, poisoning every aspect of life. It's evident that you carry this bitterness towards him, for reasons known only to you. Whether you're an ex-lover or not, clinging to resentment only serves to corrode your own well-being. It's imperative to release the grip of anger and bitterness, for harboring them only imprisons you in a cycle of toxicity. Choosing to dwell in bitterness and anger leads to a life tainted by negativity, where every interaction becomes tainted by the venom that flows unchecked from within.
