I've being feeling tired and dizzy for over a month and i've had bad diarrhea and thrown up a few times, i've also completely lost my appetite?

Go see a doctor: You should talk this over with a doctor who can do an exam and probably order some tests. Maybe it's a virus that you picked up, maybe you have gastritis, it's hard to know without further testing. If you are losing weight, that's a problem. If you aren't drinking enough, that could cause the dizziness. Drink plenty of water and call a doctor for an appointment.
