There is no reset button in life. You can't take anything back, and you can't undo anything. All of your actions have consequences, and the things you say and do today will have a lasting impact on the rest of your life
Don't ruin other people's happiness just because you can't find your own. If you can't find happiness don't be the reason someone else loses theirs be the one who encourages them and then you will find you happiness in the end.
