If at 22 your friends are married with children, they're either extremely conservative Christians or they're growing up too fast, most likely due to having done something irresponsible, and very well may be divorced with ugly custody arguments by 30.
In this day and age, it's not in any way uncommon for a 22-year-old to still be living at home. It may not be "socially cool," but it's economically responsible and better for the planet anyway.
Moving out and all that goes with it is seriously overrated, at least in part by the corporate mess that wants to sell you your very own copy of everything under the sun.
Don't give up on being independent one of these days-- chances are that if you keep trying, and learn from your mistakes ("failure" is another one of those things that's distorted in this culture-- someone who's never failed is someone who's never tried, because everyone fails, that's how we learn), you'll get there eventually.
But there isn't actually any timetable for "you must do it by XX or else." That's an illusion.
Out of me and my three closest cousins, I was the ONLY ONE who moved out by 18 and stayed moved out. If I had it all to do over again, I would have stayed home until I was about 25 (maybe older). I would have saved myself a lot of troubles, and my life would probably have been better for having done it.
Don't beat yourself up about this one. It's very common, and totally OK.
And, until about the middle of the 20th Century, it was also what the majority of people did. Moving out as soon as you reach majority is new, actually...
...and I note that it is highly correlated with the dissolution of the extended family and, some who I happen to agree with say, the dissolution of the fabric of society as well.
