Hey all, just thought I'd throw a little update!
I went to see the doctor, there's nothing wrong, just a post nasal drip caused by allergies. The doc said that I was probably exascerbating the situation due to my anxiety. Post nasal drip makes it feel like food is getting stuck. He told me there's not tons you can do for post nasal drip either but food is definately not getting stuck, it's just the awful mucous at the back of the throat making that awful feeling. He also said the white lumps in tonsils are normal in small amounts, I have large tonsils for my size I guess so I get a little more than average but they're healthy, my throat looks healthy. He's not going to put me on anxiety medication due to my age and feels that I'm better off working it out myself since I'd have to wean off the medication eventually anyway.
Since seeing the doctor yesterday though it made me feel tons better that it's not something medical and I've been able to eat whatever I've wanted since yesterday! I had a tiny bit of trouble with some salad today but I ate a good amount of it, I wouldn't have touched salad before. He recommended that I eat smaller portions throughout the day.
I really feel like just one day made a world of difference though, my fiancee offered me some of his poached eggs last night and I ate it, I wouldn't have been able to do that before. I think I would have flat out refused them

Had 2 pieces of cheesecake and been munching on BBQ chips all day (bad bad bad but I've been craving them for a good while, thought I'd spoil myself!) That's not all I've had today either so I don't feel super guilty munching on junk.
It's pretty amazing what a few words from a professional can do for you! I'll still avoid popcorn probably forever, can't stand the kernels but I've never been able to stand them

I still have the anxiety to deal with of course but I don't think it will be as bad if the rest of my days turn out like today has so far!
