Anyone else get this ?

So on August 21 I was drinking as per usual, I had quit drinking for about a month I was used to drink 4 or 5 bottles of bcardi a week , for about 2 years. Anyways I felt this feeling I hadn’t before.

Had to visit the ER, it felt like my chest was tight like my heart was having a heart attack ? , anyways symptoms got worse, After eating , when not eating enough , vision felt weird, shortness of breath, chest tightness , feeling like I’m about to faint with vision but never actually failing , I also noticed I became extremely easy to get set off balance , just being a passenger a car now made me sick, like for 2-3 mins of driving activates it. I also noticed at the beach if I looked at the sand as the wave came and washed it down if I looked at the sand standing still, it would feel as I’m falling or losing balance , it gave me fear and felt like I was gonna pass out , this happens to anything similar if I’m at a red light in my car and the car next to me starts moving , I freak out and my vision trips out.

Anyways now it goes like this as it’s slightly improved but it’s still changed my life and feels unlivable

So when I wake up not at the start of the day nothing - but after a couple of hours eating or not I get wierd vision , eating and not eating seems to trigger tightness or a feeling in my chest , gets harder to breathe and sometimes vision gets worse, sometimes i feel like I’m about to faint but I never do. Sometimes it sounds a little like ppls voices echo a bit including my own , it’s been everyday since august list this, I’ve stoped consuming sugar , soda , alcohol smoking , and anything fun ,

I’ve had a ct scan, my lungs looked at , xray, my blood looked at nothing I also had a endoscopy down my throat nothing,

Only things slightly shown were , possible high levels of blood sugar, doctor said it wasn’t enough for diabetes, went to a different doctor did a different test where I drink a sugar drink while monitored , new doctor said these results could appear as pre diabetes or diabetes he sent me to an endocrinologist, endocrinologist didn’t want to schedule me said “it’s not appropriate “

So dead end there even thou I thought for sure it would be that.

That same new doctor also did a blood test said there was not enough good cholesterol and to much bad cholesterol, but just recommended omega 3 so it’s likely not that idk what to do anymore what can this be its ruined and taken over my life

So not sure if this could be anxiety I’ve never had anxiety before I’m 24 years old , I just don’t know what to do and I’m wondering if anyone experienced anything similar
