I Have Not Been Able To Swallow Without Chocking For

I have not been able to swallow without chocking for the past 4 weeks. I lost 6ibs in a week because of it.
It all started one night when I was eating Cheetos. I chocked on 5 in a row, and decided "maybe I should stop for now"
And now I can't swallow subconsciously, I need to think about chewing and try to open my throat to actually get the food down. Some days are better than others.
Now at my 4th week I am chocking after its down my throat, unless I drink water after swallowing it feels like I can't breathe. And today I have had, ....flem? Mucus in my throat.
My mom says this is mental. I don't care I just wanna eat.....I love food. But I can't make it stop even if it is mental!!
The most I've eaten in a day was a Big Mac last week. Which was AMAZING. I just started college and I don't need this problem anymore....sorry for writing so much it's just. This has taken over my life! I can't go out to eat with friends, I can't even go to lunch or dinner, let alone snack. I can handle breakfast somehow.
Is it actually mental?
