I have really bad allergies.
Oh, I'm sorry to hear that your immune system is hypersensitive to things that usually cause no problem for others. May I ask what you are allergic to?
I am allergic to pollen and some dander. When it's pollen season my allergies go crazy.
That's bad. Things like food and medications can cause severe reactions.
Is there a strong over the counter medicine I can take?
