I'm sorry no one has answered you, and I know you are worried. It does sound like you have a lot of health issues going on, but hopefully a good Dr. can sort them out and get you on the right track.
Honestly, I'm no expert, but yes, your numbers sound pretty high. The Creatinine for sure. The BUN as well. Your kidney function is compromised at this point, but I wouldn't jump the gun and say you are in kidney failure.
The fact that your blood pressure is high is not helping matters. But I'm sure one of the first things the Dr. will do is a lot of more detailed testing of your kidney function, lots of lab work, maybe an ultrasound, and I'm sure get you on meds to get your BP under control. There are several kinds of steps the Dr. can take to get your condition under control.
And drinking lots of water until then certainly won't hurt. The iced tea should be ok, just not a huge amount.

Keeping your glucose under tight control is imperative, and cutting way down on salt is a definite plus. I would stay on any treatments your current Dr. has you on already.
Your new Dr. can work with you and get you back on track and point you in the right direction to get you in the best health he/she can. Try not to worry too much until then.
Please come back and let us know what your Dr. says.
Good luck to you. Keeping my fingers crossed for you.
