It's very difficult to get over that period if you're going to meets where instead of actually doing something everyone just buds off into little groups and talks amongst themselves. 

You legit feel like it would be rude to interject so you just don't, that puts you in a bad state of mind so that when someone comes over to talk to you because you look lonely you're extra reserved and guarded and it's not a fun time for anyone. 

The solution is simple but rare, people just have to go to a world with something to do. 
Ask here for people to go to one of those karting worlds with you, that's a fantastic icebreaker.
