I have noticed in the forums, and through talking to friends that there is a trend noticing the addictive nature of destiny. I personally was addicted, not to the RNG, or chasing rewards, this game gave me something to do each day with friends, vanguard and crucible bounties became a daily grind for my three characters and endgame content was only a highlighted undertaking on pre-arranged occasions. That said, having hours of repetitive bounties to complete each day kept me busy, and thus became my driving force to play each day. However once that got tedious I simply stopped, I had all the gear, there was no reward I was chasing, in short I had done all I needed to ages ago, so I had to ask myself why I felt I needed to log on each day to complete bounties. The answer was simple, so I stopped playing. Your situation may not be the same, you said you struggled to find other games you enjoy. You have to ask yourself what you enjoy experiencing in games and find one or multiple that tick those boxes for you and your friends. There are numerous games out there with repeatability, ones you can enjoy with friends, you just have to find them. It really all depends what your into. As for should you quit destiny or not, I can only say that Destiny is geared to fill your time and offers only a slot-machines chance of rewards you may or may not want. If you are looking for a game where you can improve your character meaningfully then RPGs are your best bet. If your wanting to shoot thing FPSs are your calling. I quit because of the lack of content and meaningful activities, you have to figure out why you play the game and if your enjoying playing it. Whatever you decide remember, games are made to be enjoyed by their players, if we simply play because we are addicted we are setting a president for future games to be tailored to repetition without content.
