yeah, it was a boner move, but you made a choice and went with it. I would be more concerned that you let them bully you after that - don't sweat it when someone makes fun of you - you can take that boner move and maybe even make some cash out of it. Rebuy, play solid, and when you have an all-in hand, might get a loose call because they remember the 5-8. Basically, forgive yourself and move on.
