Failing college and don't know what to do?

There are several things you need to understand, depending on what country you live in:
1. If you fail 5 out of 8 classes, the university/college will probably suspend you or put you on academic probation anyway, so you may not have the option to return. You need to talk to your academic advisor immediately.
2. If you are failing 5 classes, it means that you currently are not intellectually o psychologically capable of succeeding at the college level right now. Something has to change in order for you to make this possible.
3. If you have anxiety, depression, etc. you need professional care for these issues whether you stay in school or not. You can't hold down a job either if you have a mental illness. Talk to your parents and the health center at the college. You need to get help and continue with therapy.
4. No one is stuck if they don't want to be. Millions of people start college later in life or make multiple career changes. You don't have to decide about forever, you just need to may a choice about the next right step.

Call your parents or talk to them if you live at home. Go see your advisor or academic counseling and get a clear understanding of your options.

Eight classes is too many to take in one semester of college. No wonder you're having trouble. Take fewer classes per semester.

8 classes?!? Have you stopped to think that maybe you're taking way too many classes at once?

At my college, 3-5 classes (12-15 credits) was considered a full load. And if you wanted to go above that you needed special approval from your advisor.

I would say you should talk with your advisor. Cut your losses and withdraw from the classes that you are failing and just focus on the remaining classes.

You will end up with a "W" on your transcript and will have to retake those classes later, but they won't negatively affect your GPA (at least not for now.)

Also talk with your advisor about setting up a REASONABLE schedule of classes. And maybe take a few (FEW!) classes over the summer to help get you back on track.

Don't worry about what people are going to think of you now. Just focus on recovering, and doing better in the future. Everyone stumbles now and then. What's more important is that you can pick yourself up and keep going.

Consider joining the military.
All your survival needs will be met: housing, food, medical/dental/vision care, work clothing, work transportation, etc. You will receive a steady paycheck, and you should be able to save most of it. You will attain the best physical condition of your life, learn to do something constructive.
When your enlistment is up, the GI Bill will PAY FOR your education, AND you will have veterans hiring preference at many employers.

Everyone in the workforce feels stuck in a job they hate and aren't happy.  (Yes, even those who graduated from college)  What's the difference if you get stuck in a crappy job now or later?  Resistance is futile.

I know exactly how you feel. I started college in the fall of 2015. It’s 2018 and guess what. I am still in college. You should still go to college. Just take less classes, get a tutor, meet people who will help you in your classes and most importantly don’t be afraid to talk to your professors because there job is to help and answer questions. If your professors are mean and doesn’t want to help (which that happened to me lots of times) talk to your classmates. As for quizzes and tests find a study buddy who you can study with. Good luck and know that you are not alone. I know lots of people who dropped out of college. Don’t be that person.

You are right . Getting a job when you have not fully trained for the position is frustrating in the long run. You will be met with a situation where after working for years, someone else is employed tomorrow and gets to be your boss simply because he fully got trained in the trade. You can supplement your studies by enrolling in online classes at the same time as your full college studies. CourseHero.com for example has answers to various college assignments.
