Allergic reaction?!

Hey guys, so I’m trying not to freak out but... I’ve never had any allergies to peanuts before, and yesterday I took a bite of a Thai noodle salad that had peanut sauce on it, and I’ve been itchy under my chin, and have this horrible cough. I didn’t think much of it, but later in the day I had peanut butter ice cream, and then my entire body went super itchy, I felt sick, and got hives under my chin... I took 2 Benadryl last night, and fell asleep, but when I woke up this morning I feel so sick like I’m about to puke, I’m still itchy and still have a horrible cough and scratchy throat. I’m not quite sure what to do 😪 what do you think? Should I go to the doctor?
