You have shorted all LEDs. This is not a parallel connection of the LEDs yet. ![enter image description here][1]
Again 3V LED can't tolerate 120V. If you want to connect those LEDs in parallel then you have to use 3V supply. One more thing is that you have to keep in mind the current rating of the supply. If you want to connect too many LEDs in parallel then it requires more current.
