Hi sorry to here about your problems, when protein is found in your urine it can be a sign of infection or that your renal function has dropped but this could be with your unstable diabetes. So do not panic, i found that when i was getting problems with my diabetes the first thing they seem to do is change insulin for another type. Diabetes is a big concern for hospital and sometimes i think that the powers that been get a good deal off one insulin supplier, so they change to that make. Now when you see your new doctor explain what has been going on and tell him how you feel( take a list of things you want to talk about). If the doctor changes your insulin doses which is the norm, ask them about going on a diabetic pump, which will give you better control over your diabetes. If they say no and you are not happy about it you can go to your GP and ask to be sent to another hospital for your treatment( i moved from north Durham to Newcastle about 6 years a go and since then its been great, about a extra 20 mins from home but its worth it) If you are worried about your renal function ask the doctor to refer you for your own piece of mind and if you are denied a insulin pump get in contact with your local MP and explain that you think it will benefit you as some hospital will not give them due to costs. There is a common link between diabetes and depression so ask to be refered to a mental health team i have done it and it helps me. The blood pressure tablets are the normal thing that you get when protein in your urine, they all so might give you Asprin to thin the blood. The main thing is that ou have a choice of what care you have and where you get it so if you think that you are not getting what you need then change it.
