Short of seeing a doctor (no money and they took my insurance away) what can I do about this and what is the limit of what a person in this shape can take before doing damages? High blood pressure 182 over 104, low fever , vomiting ,watery stool dizzy and stumbling and sever migraine head ache. What can I do at home?

There is nothing you can do at home. You should seek emergency medical treatment. Hospitals have programs in effect to help the uninsured and underinsured.

How can they take you Medicare away?

First where is this at. If US, they do not take medicare away. If it is another plan to go with medicare ? Only lose if, if you stop paying.

But, they just need to go to the doctor.

Agree with all the above.
PLUS whenever you have vomiting and diarrhea, you must keep hydrated by drinking tons of weak liquids like clear broth or very watered down juices. That could be causing your headaches. The rest is what needs immediate treatment. Do an hour of drinking before you go.
