I can definitely understand how frustrating this must be! Based on the fact that you stated it isn't intentional, it sounds like there may be an underlying medical cause. While I think it's great that hearing about rumination disorder on Discord encouraged you to do some research, I would highly recommend asking your parents to make an appointment for you to see your doctor, as relying solely on the Internet can cause us to inaccurately self-diagnose.

Because this is involuntary and is causing unwanted effects in your life, such as struggling to sing or talk after eating, I doubt anyone will view you as attention-seeking. It sounds like you just want to understand what's going on in your body and if there are any ways to reduce symptoms. If your parents are able to take you to your primary care physician, that would be a great first step! During your appointment, you can tell your doctor about the symptoms you're experiencing, as well as how long you've been experiencing these symptoms and the side effects that have come up along with it. This is also a great opportunity to give your doctor any relevant information, including the frequency that you experience symptoms, any patterns that you've noticed such as time of day or type of food, and any concerns that you have about the way it is impacting you.

It's entirely possible that your doctor may want to run some tests to help narrow down the cause. However, they may also choose to refer you to a specialist. If you do receive a referral, be aware that it isn't necessarily a sign of something seriously wrong! Instead, your doctor may not have the expertise in the digestive system to be able to treat you properly. If they do send you to a specialist, your doctor may just be doing their best to ensure that you receive the best care/treatment possible from a doctor who does have an area of expertise in your specific issue or the digestive system in general.

Even if you don't receive a diagnosis, being seen by your doctor may help provide you with some peace of mind. Additionally, even if there isn't an underlying medical cause, your doctor may be able to provide you with some suggestions for symptom reduction.

Wishing you the best of luck if you do choose to get checked out!
