Not necessarily, What actually creates regret is expressing them from a place of desperation, expecting a specific response, or saying more than you actually wanted to reveal.
Never saying it at all is another type of regret that leaves u with thousands of unanswered questions
It's not getting better, distract urself from it as much as u can, stay busy as long as u could, prtend ur fine and happy,
but when ur alone with ur mind, u do know u r not recovering from this loss, not this one.
