No, it is not possible to be allergic to blood. Your immune system violently reacts to the allergens you are allergic to. If anyone were allergic to blood, they'd be dead by now.
But it is possible to have a phobia of blood.

I think so because I been having very severe allergic reactions and my blood pressure get super high and then when I use the epi-pen it drops until I go into shock.

Sometimes problems occur with a blood transfusion, but that is supposed to be rare. Some people can have an allergic reaction to the transfusion.
Every blood transfusion carries the risk of allergic reaction, to anaphylactic shock, even if blood type is perfectly matched. If medication was also infused along with the blood, and the patient had an allergic reaction, it would be impossible to tell which sustance was causing the reaction: the blood? or the medication? Remember that every transfusion reaction can be deadly. As well, some meds may break down blood components. Therefore, never inject IV meds into a transfusion tubing or combine medications into a blood transfusion set.
