I think I’m dying even though my physical symptoms are normal. Please someone help me.

For the past day or two my anxiety has been TERRIBLE. Ive been having vision changes, I’ve been crying uncontrollably, I don’t want to go outside, being inside too long makes me feel lonely which triggers my anxiety/depression. I keep having these headaches that’ll last for WEEKS—some days will be better than others. I try avoiding pain killers bc they either make my anxiety worse or dont do anything for my symptoms since my symptoms is just an illusion in a way.

Last night I had a pretty bad panic attack, truly believing I was going to die. My family isnt making me feel any better, everytime I beg to go back to the ER/doctor they make me feel like im burdening them. I really dont feel safe cause no one will listen to me. Right now im not feeling any painful or severe symptoms besides a minor migraine, blurry vision(only in one eye), and feeling like my ears are clogged. I tend to convince myself that I have a brain tumor or I have another mental illness thats causing me to behave the way I am.

Everytime I mention anything to my mom or cry to my mom she gets upset at me for stressing her out and refuses to take me back to the emergency room(which I somewhat understand) but it feels like I have to drop dead or have a seizure for anyone to listen to me.

I feel like I can’t complain bc I brought it on myself due to the lack of wanting to socialize with actual people and doing what normal teens do but I dont know how to make myself feel better until I get taken in for therapy. Please someone help me im extremely terrified. Please someone help me.
