worried about CCI, cervical misalignment causing symptoms, can you still smoke/drink with issues like this? please read.

M18, Currently taking Escitalopram, Gabapentin, Risperidol, have been taking concerta but stopped for a few days.

I have been cracking my neck and back for a while, not that its needed but if you see my previous posts you will see my concerns, i am basically still dealing with the same thing. I have been doing movements as a result of my OCD to my neck and back, and when i move my neck in certain ways it consistently clicks. I am worried about an upper cervical misalignment, or some cervical issue that is obstructing blood flow to my brain. When i stand up i often get very dizzy, and sometimes i crough down to get rid of it, sometimes it makes my hearing muffled for a bit as well. Im just very worried about a cervical issue affecting blood flow to my brain. I have felt weak and just sickly for a few weeks now, it got better for one week but now it is back. I just don't know the cause. I had a dr appt recently, and i mentioned this all to my dr and that i was worried about a misalignment or an artery issue, and he said that it was not the case, he said it is possible and people have had artery dissections from it, but he personally in his years has never seen someone do it to themselves. So i let it go for a while, then i had a lymph node under my jaw swell up (it has since went down) and i accidentally did a movement with my neck that i had stopped doing for a while, and im not sure if thats what made me sick, i have no idea whats going on.

I had a dr appt 3-4 months ago in the ER because i was worried about lymphoma, had blood work and chest x ray which was clear

My recent appt they checked my BP and oxygen and they were both normal

I had a neck x ray a few years back when i was concerned about crepitus and clicking sounds which they said was normal

I had a CT scan on my head when i was young because of frequent migraines and concerns about a tumor, they said my head was "pristine"

I had a friend mention high cortisol, but i know that is usually caused by tumors, and now im horrified i have a tumor that was missed by the CT or that i have developed since, as i was young when i had it done. Im not sure if that could be it. I can't tell if it could be just anxiety or what

Symptoms:
Weak feeling in body and legs

Dizziness when standing and sometimes muffled hearing (has since gotten better)

Consistent clicking/crunching in neck

headache when coughing (comes and goes)

just overall don't feel well, fell sickly, no cough or flu symptoms, just feel sick.

I smoke weed every day, and i drink alcohol. I have been drinking more lately since this all happened because im so stressed out about it. I havent drank in a while and i drank last night and it feels like the alcohol isnt working. My question is even WITH the things i am worried about, would weed and alcohol still work the same? should i still be able to get drunk? im wondering if its a physical or medical issue that is making the alcohol not work. Would it work on anyone regardless? is it medication related?

Someone please help me out here, willing to answer questions or chat about this, just need to be able to feel better, need to know if alcohol will still work while i wait for my next appt to ask everything i need to ask, bc it feels like its not working.
