Even after I brush my teeth (colgatevtoothpaste, colgate brush and listerine afterwards)my breath gets stinky fast, what might I have?

Many reasons. I noticed you said brushed your teeth but bot flossed. If cause of odor is from your oral cavity brushing the tongue and proper flossing may help. You may also have sinus problems, diabetes, or digestive issues. All of these can cause odor issues. A dental first with a medical follow-up would be advised if not resolved.
Esoph diverticulum. You have halitosis which could be caused by disorders of the upper GI tract, such as an esophageal diverticulum or achalasia. You may need a barium swallow and upper endoscopy. Arrange an appointment with a gastroenterologist.
