Hi, I am a first year graduate students and I have a huge qualifying exam in three days. For about a week, I have been experiencing periods where it feels like my throat is closing up and I am about to pass out. They normally last an hour, maybe two, but I don t actually have any trouble breathing or swallowing, it just feels like I do. I think I am just having panic attacks, most of my family struggles with and is medicated for various types of anxiety disorders. I guess I am just looking for some confirmation that this is most likely what is going on. The last time it happened I was drinking coffee, and this time I just ate some peanut m&ms s. The overactive brain inside me is convinced I m going into anaphylactic shock, but I ate peanut butter every day last week, and nothing happened, and I don t have any known food allergies, so I feel like that s pretty unlikely. Thank you
