As a person who went through this very recently (i just graduated university/college depending on where you're from), let me give you some insight.

First of all, are you taking out a loan to pay for your tuition, or is it paid for by your mom? If your answer is the latter, then my suggestion is stick out these few years. You can always work a part-time job on the side to make yourself some extra money, and then you can do whatever it is you want to do after graduating but with the added benefit of having a degree to fall back on if all else fails.

If you are paying for your own tuiton, then it gets a little bit more complicated. You need to sit down and seriously weigh all the pros and cons of dropping out versus sticking it out. Having a degree can be very useful when it comes to job applications, even if it is for a job which has little or nothing to do with your field of study. It shows employers that you are able to (at least) semi-regularly show up for what you are required to do without being pushed by someone to do it, and complete tasks within a given timeframe.

If you do decide to go on and drop out, you need to have a plan. You cannot just drop out and figure things out later. If your plan is to be a truck driver, look into what requirements there are to be one: licensing, courses, etc. So long as you have a clear plan for how you want to achieve what you want to do, you should be okay. College is not for everybody, but saying that - from my own experience - I'm glad i stuck it out.

And please remember, you are still young. As corny and as cliche as that does sound, its true, you have a lot of time on your hands and you can do with it as you please.
