IMMUNE DEFICIENCY PLEASE ANSWER!!!?

since march i have been having many recurring infections, like shinglesx3, appendicitis, constant sinus infections, weight fluctuation, anemia, acid reflux, frequent skin rashes, chronic sluggishness and l infections. my doctor recommended me to an immuniologist because she thought it was unusual i would get shingles three times when im only 14 years old. also i got many infections when i was really young. im getting blood work done on monday but i was wondering if anyone knew what this might be? please help i dont want to be sick anymore!
