There are some days where we just sit down and wonder what our lives would be like is we did somethings in the past a bit differently. Don’t feel lonely because it happens to everyone. Your regret might be showing someone you care or even saying YES instead of no.
But the good news is that you are not alone and it’s not too late to make those changes because you’re still alive. Accept that you can’t change the past and make sure that you don’t repeat the same mistake twice.
