Sunny is absolutely right, sounds like a lick of a type of OCD. I'm so very sorry to hear that, but work yourself into thinking the functions your body does. Your esophagus works like a water wave, it works food downward in a forceful motion. especially at your age your are perfectly healthy to swallow anything. There are people who can swallow ungodly things and have not suffered. I mean if you're looking into swallowing pool balls, skip the cue ball because it's slightly bigger.
Have you noticed yourself trying to cutting your food into smaller pieces? If you're eating drier food and you feel that it's a bit tough to go down, have a glass of water to flush it down, think of it as a solid force working your food down, there's no stopping it. Your epiglottis is there to keep you from choking.
You've got to push past that fear and nourish yourself, even if it's just soup or something.
Was there ever a traumatic experience that triggered this? Even if you think about it once or think you're choking you'll always have that fear of doing it again, that's a definite anxiety. anxiety keeps us alive.
I'm only 16 so I can't call my psychiatrist or go when I want and my parents don't wanna take me.
You need to be straight forward with them and tell them that you have a serious issue. It is there absolute RESPONSIBILITY to make sure that you are healthy and comfortable. especially being a minor. I suggest you talking to a grandparent or an uncle that you trust and see if you can route in from there.
If your parents have insurance, then get that information and get to a psychiatrist. Schedule your appointment NOW... Psychiatrists are often very busy and you might be on a few weeks out... maybe not, depending on where you live. but seriously.
Today... get a hold of someone and go from there. This won't get better on your own, and speaking with a psychiatrist will definitely ease your anxiety and help you out.
You let me know what the outcome is, your parents should allow you the right to seek help any time something is wrong.
Especially if you have insurance all you'll have to pay is like a $25-$30 co-pay at the office. It's not really that expensive.
I don't suggest a General Physician (for example like a medical center or a hospital) or your family doctor as they don't really specialize in this... they may help you with something but to be set on a plan with that a snowball has a better chance in hell.
Get help today. get back on here and let me know how it turns out. Please.
I hate to see you struggle.
