I Checked My Blood Pressure After Having Sweets And It Was 367.Is This OK?

Well here is the thing... my boss has diabetes so he has his little checking device, and playing around i told him to check my level which he did. Now just before that i had like a half pound of cherries and two horchatas (mexican flavored drinks--very sweet) and he checked my blood sugar like 25 minutes after eaten all that and it read 367 so im freaked out......... i mean im a 250lbs pound guy 6 ft tall but i hardly feel tired or sleepy or anything my boss feels when his blood level is too high.... am i freaking out too much or should i consider going to the doctor.....
