She said the results were negative.Her family is now calling on Pasadena ISD to change its policies.Garcia and her attorney held a news conference to discuss the diagnosis on Wednesday."They were telling me that I was under the influence of something, when I didn't do nothing," Garcia said.Garcia's attorney credits Eyewitness News viewers with helping with her case."After I looked up what the viewers were saying it is, I was like, yeah, these are the symptoms down to a tee," attorney Gene Wu said.Wu said Garcia is diagnosed with Postural Orthostatic Tachycardia Syndrome, also known as POTS.Rachel Ainsworth reached out after our original story because she suffers from POTS herself."I was fired from jobs," Ainsworth said. "I was accused of being on drugs. I was told I was lazy, dramatic."POTS is primarily found in women ages 15 to 50 years old.It's a condition that impacts the cardiovascular system.It causes the heart to work harder after a person stands, which can cause people to faint, get dizzy or be fatigued - symptoms Jazmin said she suffers from.The district let her go back to school. It wouldn't give Eyewitness News an interview but sent a statement:Ainsworth said school won't be Garcia's only issue.She said it'll be an uphill climb because many still don't understand her condition."If you're feeling these symptoms people are telling you that you're making it up," Ainsworth said. "They don't believe you. Believe in yourself, and have the confidence to fight."
