You need to find other games to play. It's actually insane that you haven't, considering that you're right: Destiny is garbage these days. There are so many great experiences out there you could be having right now, with or without friends, that it's really hard to conjure up the courtesy of support especially when this is basically what you've been told over and over again in other similar threads you've made. You haven't shown that you've been trying, frankly. Go pick up Division 2 (for all of 3 bucks) and play it; it's good whether you have friends or not. Download a trial for Final Fantasy XIV and get lost in that world for a couple hundred hours while you blow off steam. Too slow for you? Pick up Remnant: From the Ashes, a game that couldn't wink and nod harder at OG Destiny if it tried. Don't like third-person shooters? Then grab DOOM 2016 and rediscover what makes first-person shooters good in the first place.
Your problem is you're so dug in with something that sucks you can't see how much is out there that doesn't. You need to put that game down, and force yourself to try something else. If you're *really* trying, you'll find that happiness is a by-product of playing great games, not some emotion monopolized by the Destiny Gods.
Give Destiny a break, but more importantly, realize that Destiny isn't making you happy anymore and it's time find something that will. Acting like there's nothing else out there you can have fun with is beyond bogus: it's for lack of trying and, frankly.
