Sounds like you should quit if you think there's a reasonable chance to get a more satisfying job. Only you can guestimate that but I'd start with trying to get in contact with the old company you worked for. It sounds like that was enjoyable and you could move there now. It may feel odd to return to a place you left but assuming you left nicely companies you worked for are usually pretty happy to get ex-employees back (because there's no "risk" and they know who they get)
