I feel for you but there are some jobs some people can not do. This is one job where your health should not compromise the safety of those in your plane or those on the ground. Be it a peanut allergy, dicky heart, or epilepsy it doesn't matter. If there is a reasonable chance you will have a seizure you cannot do this job. If a medic states you will not have seizure through contact with peanuts then that's fine. But if not, then you may have to accept that flying without restrictions is not possible.
