Hell is never a nasty surprise waiting for a basically happy person. Hell can only be the full flowering of a pride and selfishness that have, through a long time, twisted a heart so thoroughly that it considers happiness as unhappiness and has an arrogant disdain for happy people. If you are essentially warm of heart this side of eternity, you need not fear that a dreadful fate awaits you on the other side because somewhere along the line, unknowingly, you missed the boat and your life went terribly wrong.
