My daughter (with ME/CFS) is an undergrad and I taught undergrads for years before I was ill. I recognized the attitude.
There are resources at this link for students with dysautonomia, which you may have since you talk of dizziness and related symptoms.

Some of these articles are aimed at college students.
I suggest that you take some time to read through the many informational threads here. You may find many of your questions already answered.
This is a discussion forum. There are also chatrooms available here for, well, chatting. They are a great place to go when you are bored or discouraged and are looking for some immediate human contact.
My daughter goes to college near home because she would not have been able to take care of herself appropriately 4000 miles from home. You may find yourself in the same situation. Living in the dorm, as uncool as that might be, is another option some undergrads with ME/CFS use to manage self-care.
Have you been formally diagnosed? You may be able to get some resources from your college as a disabled student.
We are fortunate that my husband has taken care of us during the 6-7 years my daughter and I have been ill. Without him, during periods when I was bedbound or housebound, I would have had to go out to do rare, minimal self-care activities such as medical care or shopping. It would have been at great cost to my health. Many PWCs DO have to go out when they are technically housebound, even if they spend the next several weeks/months recovering, because they have no choice. It's a tragedy.
There are many sad and amazing stories to be had here. I suggest you take some time to read the threads and discover them. Some of the people here struggle daily against incredible odds. You will learn a lot about the tragic and courageous face of ME/CFS.
PS Many of these people, such as Wonko and Sushi in above posts, deserve a great deal of respect for the strength and knowledge that have allowed them to survive under conditions that you probably can't (and hopefully won't) begin to imagine.
