My WBC Count Has Been Going Between 21-24 And My

My WBC count has been going between 21-24 and my c-protein is currently at 3.4. I also have experience sob and digestive issues resulting in ulcers. I'm 33 5"2 and 120# and run after 2 children and maintain a PT job. I am also a smoker. Doctors have explained fibromyalgia in the past but it's also the same doctors who make you feel your sx are crazy or invalid. I have been working at a bar for 2 years which MAJOR black mold was discovered. We as employees were asked to come to a cleaning party where we all needed to pull everything out and clean this caked on black mold. At this party I discovered other ppls sx they have been dealing with. Migraines etc. I have been put on IV antibiotics as well as oral antibiotics and anti-inflammatory but still feel nausea/fatigue/frontal headaches/sob at times. Just not normal. Severe painful inflammation in my neck. Doctors are starting to chalk this up as stress. Should I be pressing the issues of my sx and keep trying to find someone to listen or I am going crazy?
