Im 15 and my blood pressure 138/63. im worried!?

im not what you would call obese but im slightly overweight. i have a very strange diet that in some places is very healthy and some is very unhealthy. i drink about 1 litre of orange juice a day and i eat about 3bits of fruit a day. but i eat chips every day and i put a lot of salt on them. however im a vegetarian and i eat 5 vegetarian sausages a day and there pretty much made of vegetables. also i do quite a lot of exercise, i play badminton for 2 hours a week and i walk about a mile a day and i cycle every Sunday for about 4 hours.
