How many game you finshed so far? How long have you been making games? These questions are rather important because if you never made a fully finished and playable game then starting a studio is a suicide. There is also this antisocial thing, working alone on your own indeed put a social stress on you (I know of some indie devs who keep a normal job for the purpose of working with people and not falling into madness :D).
In your case I would probably found a normal real job not related to games and in the sapare time make a game as a hobby (under clear deadline). Then based on how much I loathe my daily job and how successful I was in making the game in spare time I would decide the next step.
Also, as some people above said, you can change your mind later
