Sounds like for the good of your own mental health its time to find another living space anyway. It may be best for everyone concerned.

In the U.S. endoscopies are typically done under light sedation. You wouldn't even be aware of what's going on or remember it.

Thank you both so much,for the helpful advice on this topic & I am happy that it's not in my head,on my body telling me that something is up with my symptoms & needs a doctor's input on. I have a strong feeling in my gut,that my symptoms are either related to a gluten sensitivity,or even Celiac Disease itself. I am keeping a detailed track of my symptoms,& what foods I ate that triggered them to happen, because I know this will help me to better answer my doctor's questions on my symptoms. I am gonna ask for the blood test,& I am a little nervous lol about maybe having to get the Endoscopy but honestly if the blood test & Endoscopy helps diagnose whatever issues going on with my digestive system & the rest of my body,& why I haven't felt good in what feels like forever,then I will gladly get whatever diagnostic procedure needed. I will keep everyone updated on the doctor appointment & if there ends up being a diagnosis😊

Thank you. They said I'm gonna be kicked out but I have to find somewhere else to live anyway.

Yes, IMO, you need to quit and look for another job. You can't put a price on your health. It's unfortunate that your parents don't understand but they don't have to live with the ravages of unattended celiac disease. Sometimes you have to do what you have to do and just be willing to live with the fact that some people will not understand. I don't know your age but that's being an adult and taking ownership of your life.
