nervous about blood tests

i have my annual bloodtests approaching this tuesday, to check on my diabetes and other things, my vital organs presumably....i reversed the diabetes years and years ago through hard work, exercise and watching my diet, but ive gained back 2 stone in weight after losing 3 stone intitially and reversing the diabetes...now ive gained 2 stone back in weight.

so bottom line is i'm afraid they might find a problem in my bloodtests? plus i'm scared of anything clinical....just a phobia i have.

can you help or give some kind advice?
