I hate people too. Well, some of the time. Maybe hate is too strong a word but interacting with people is definitely not one of my strengths, and it usually tires me out quickly. Over the years I've learned to overcome it but I'm definitely more on the introvert end of the scale.
That said, I do find that multiplayer online games can be fun. There are a lot of games that are multiplayer-optional too. Minecraft for instance will even let you start in single-player mode, then if you like you can open your single-player game up to other players on your local LAN. Ultimately of course Microsoft would like you to rent yourself a "realms" server from them and play online with a bunch of your friends (even friends not on your LAN), but they make it easy to start single-player and take baby-steps toward multiplayer as you're ready. Something like that might be good to start with. In fact, some of my best experiences with multiplayer gaming have been in "LAN party" mode, not MMO games per-se.
I would even say stay away from most of the big-name MMO games if you're at all unsure of yourself. Especially games like fortnite or PUBG that are highly competitive by design - arena-style "battle royale" or "last man standing" - can be quite intimidating to get into multiplayer. They can be fun once you do get familiar with it and I'm not saying stay away forever but I wouldn't make something like that my first choice. Unless you like learning to swim by jumping in the deep end of the pool of course. (For me they're boring too because there's no story or progression of any sort, just repetitive kill-or-be-killed on the same map(s) over and over. But that's more a personal preference sort of thing. Some people do enjoy that.)
