when all is said and done

Have you ever made a decision that you knew was right for you... but at the end of the night, you still kinda regretted it? It is weird... when I made this decision I was excited to make it, certain I had done the right thing, even a bit proud of myself. Then later on that evening, you find out stuff - and you question your decision. I really dislike that feeling, of questioning what I know is right for me. What is wrong with me??? (that is rhetorical, please don't answer...) Regardless, I am still proud of my decision. I am happy with what I did, just questioning the what if's....
