Trouble Swallowing Food For The Past 5 Days?

Okay so a couple of days ago I posted this question with answers telling me that it was all in my head and it'd go away, but it hasn't. It's been five days and I've been having trouble swallowing certain/most foods. I can eat cereal, a whoopie pie, and starbursts but pretty much anything else I can't swallow. I tried to eat dinner tonight and choked on broccoli and mac n cheese. I choked on pizza and chicken today too. It's like every time I try to swallow the food I physically can't swallow it. It ends up sliding down my throat and I choke, gag, and bring it back up. But with the mac n cheese if I didn't chew it and just swallowed it pretty much whole it worked. I can swallow liquids. My mom has the same problem and wants to take me to the doctor to figure out for sure what's wrong with the both of us. My dad thinks for me it's psychological because I have a pretty bad phobia of vomit and he thinks that that's causing me to not be able to swallow because if I eat I could throw up. He also thinks it could be me thinking I'll get fat if I eat, but I doubt that. What could it be?
