hehe. Something is amiss.
O is recessive. A and B are codominate.
To be true O, your genotype is OO.
To be B, your genotype is BB or BO.
To be A, your genotype is AA or AO.
To be AB, your genotype is AB.
So one of your parents have to have B allelle. If either of your parents are OB (then in reality one of your parents is blood type B not O.), then it is possible that you are blood type B.
If not, well, your patients raised you and you consider them your parents. Does it really matter that one of your parent is not you biological parent. Talk to them. Be patient and they may explain things to you when you get older.

First of all, if the original testing was done as part of a class lab experiment, the results are not always 100% acccurate, and can cause confusion, so if that is where any of these results came from, no worries until a professional typing is done.
No matter what, before panicking or worrying over whether your parents really are your genetic material donors, I would suggest having both your blood and your parents' blood re-typed in either a professional lab or at your doctor's office. It is just about impossible (barring mutations of some sort), for two parents with an O blood type to have a B-type child. The O blood type is recessive and is never expressed if the gene for A or B blood type is present. It is definitely possible for two As, two Bs, or an A and a B to have an O child, but not for two Os.
If, after all three of you are re-typed, the results are the same, you may want to sit your parents down and ask some serious questions about your parentage. It is possible that they have chosen not to share something about your birth with you, such as adoption, either because they were waiting for you to reach an age where you could understand it, or simply because they were unsure how to handle difficult questions about it.
If there appears to be no other explanation, it would be entirely appropriate to ask your doctor about it, as I believe there is a very, very small chance that a genetic mutation could cause your blood to either type incorrectly, or to type as something that appears impossible. If this is the case, you may want to have a complete genetic work-up performed, especially if you are planning to become a parent, as you may need to determine if you have a genetic anomaly that could transmit to your children.
Determining the correct blood type for your whole family is very important, as that information can be critical in an emergency, so it would probably be wise to be re-typed as soon as possible and to get the correct blood types into your medical records.
Good luck!

The ABO Blood Types
Each person receives an A, a B, or an O gene from each parent.
The A and B genes are co-dominant, and the O gene is recessive.
A person whose genetic type is either AA or AO will have blood type A, those with genetic type BB or BO will have blood type B, and only those with genetic type OO will have blood type O.
A child with type O blood can have parents with type A, type B, or type O blood, but not type AB. Conversely, if two parents both have type O blood, all their children will have type O blood.

IF they are both O and you are not some one is lying or an error in the typing has occurred. O is the recessive alleal in humans so if both parents are O they hold OO genes so no A or B offspring are possible

Don't listen to that other person who said your parents are lying to you. Both my parents are O+ and all my 4 siblings and I are A- or A+. Blood types are recessive and can come from grandparents, aunts, uncles etc.

Go to Red Cross all three of you and get a blood type for it seems someone is confused.
I agree with Julius, A and B are dominant over O and if both are together, they result in AB

Your parents have a recessive gene for type b blood.
Example: Your mom is OB and your dad is OB, you could have O or B type blood.

Obviously your parents are lying to you and one of them isn't really your parent!!!!

genetic probability, just cause your parents have blue eyes doesnt mean you will.

Yeah that is basically impossible...you should get it checked again or get them checked again because someone is mistaken...
