Why do i need an epipen for a peanut allergy (no anaphylaxis)?

Though you have not experienced anaphylaxis yet, the possibility is still there with this type of allergy. The specialist is not being too cautious. The more you are exposed to peanuts, generally the worse the allergic reaction will become. Requesting your G.P. to send you to another specialist is one option. I doubt another specialist will come to a different conclusion however. On the other hand, they may give you your note, as I am not a physician and don't know the exact policy for that sort of thing. There isn't any harm in asking your G.P. about it. Hope this helps.
