Insure_America,Hello and welcome. I agree with the wisdom of the members who have posted before me. I do feel you have to deal with the BP and if that means starting on medication or whatever your Dr. advises you then I would follow his/her plan.
Most physicians will prescribe a low sodium diet for high BP. Here is a link to a low sodium eating plan.

As far as dx your self as diabetic, I would also strongly advice you to be tested by you Dr. to confirm this.
Controling your anxiey is key to dealing with any medical problem so I do hope you check out some of our resources to help you learn how to reduce your anxiety.
Keep on talking with us.
Kindly,
