How quickly does anaphylaxis happen? i ate something 6 hours ago, and i am starting to feel like i am having an allergic reaction.

Usually minutes: Rarely few hours, so unlikely that what you are experiencing is related to what you ate, at any rate it is wise to keep an antihistaminic handy, and probably epinephrine pen in case you are prone to anaphylaxis, and see an allergist if you really suffer, good luck
