I am 28 and feel exactly like you: one difference, I have never gone on my own, I have always been an employee at a huge corporation.

Right now, I look up to you a lot, you had the balls to go on your own.

I don't have a solution to this, I can only let you know that you are not alone and I relate 100%. I would get a 9to5 job, save some money, and quit and travel for a while, find your passion. This is what I hope to do, hopefully soon
