I Have Been Visiting Dr. On Reg Basis For Some

i have been visiting dr. on reg basis for some years (gen. and heart dr.).I am on several meds for heart and blood pressure and type 2 diabetes.everything had been regulated until I recently went to regular doc after I had been in hospital with shortness of breath. that was remedied okay but lately my blood pressure is registering around 90/60 fairly regularly. heart dr. said (after it rose a little after I stood) that was a good sign and wasn't to worry. but all my checks at homenever get above the 90's over 60's. am I just a worry wart?
