Accepting that toxic love is not love to hold onto is where I found relief from pain.

It acceptance feels like being bathed in balm, so peaceful and calm and serene to no longer be clinging tight to pain. Letting go is terrifying, but the freefall of freedom and uncertainty can also feel like flying with the wind brushing past you.
