I don't know your exact life situation, but in most cases, people get into startups for three reasons 1) they have a burning desire to be their own boss and control their own destiny 2) they see an opportunity in the marketplace and/or have a product idea they want to bring out into the world 3) need money to survive (pay rent, food etc) and a startup could provide a quick income source.
If at this stage in life you are in constant need of direction and instruction, don't have a business idea, and you are getting financial support to further your education - stay where you are for the time being and ride out the confusion.
BTW, I am an experienced serial entrepreneur and probably twice your age.
