Weakness, gas, diarrhea, numbness, nervousness. Are all of these symptoms of anxiety because I have an anxiety disorder. I also was sleep deprived^?

Anxiety IS a symptom. There may be connections between all or some of these complaints. Also, being deprived of adequate sleep (or any other need for a healthy body) matters. Naming a set of problems helps sum it up, but it won't fix anything. You really need to see a psychotherapist, perhaps get rx help and stick to a daily healthy life plan for eating, sleeping, etc. You're aging too quickly, slow down, calm down.
