Umm is this normal or because of my problem?

Hiiii! My boyfriend and I hav had our first kiss and everything but still every time we kiss I sorta faint or get dizzy and black out...? But I'm also hypoglycemic. And when we kiss I get nervous and I faint sometimes when I'm nervous. And for hypoglycemia I'm supposed to have candy with me but I never do because I don't like candy. So is this my nervousness or hypoglycemia?
