Food Allergies Treatment

I have a peanut allergy, and sometimes it seems like my parents don’t think its a very big deal. We still have food with peanuts in the house and it makes me very uncomfortable. I don’t even feel safe at home. What should I do?
I’m very allergic.
i think it might also be because i’ve never had a reaction (i’m very careful), so they don’t think it will happen.
