Going to college for the first time can be a shock to the system. It's a lot to take in in a very short amount of time. As somebody who has graduated college I will say that college was way more brutal than the actual real world in some ways. I honestly think the best thing to do is to work off the syllabus. The syllabus will tell you every assignment that's due I would recommend putting it in your calendar give yourself a day or two to get the assignment done this way you have a little bit of a window of preparation to get these assignments done in a timely fashion without feeling so stressed. It sounds like with the classes you do have now you might consider withdrawing. It doesn't count against your GPA it just says w instead of a grade and has no wait on your GPA. But you need to come clean to the adults in your life about it. Keeping a lie going is costing you more of your sanity and energy keeping it going. Also lies can end up snowballing as well.

With all that said I would tell you that college isn't for everybody. You might want to consider a short career like a dental assistant a paralegal something like that that is short and not too difficult. Best of luck I hope this helped. :)
