I know the rules say " don't ask for medical diagnoses", but i was just wondering if anyone felt the same way.

The thing is I've been feeling shit for 3 years now. It began with some dizziness attacks and weird feelings in my chest, like something is bubbling for a few seconds in there.
Then i was smoking some weed with a friend and i crouched down to get a switch-controller, suddenly a wave of dizziness hit me and i had to lay down, suddenly my legs started to jerk uncontrollably for almost half an hour, but my heart wasn't racing and i wasn't hyperventilating.
I stopped smoking weed on that exact day and had to call in sick for work for almost a month. I was at my GP at a daily basis and he gave me some SSRIs, they didn't help.
I was going back to work after 3 weeks, but i wasn't feeling any better.
What happened next was a journey to 3 different neurologists, 2 MRI scans, and a Neurosurgeon.
One diagnosed me with a masked depression, one with anxiety/panic disorder and the third one with GAD. The MRI scans showed that i had a rare malformation in the brain, called Chiari-malformation where a bone in the back of my head presses down on the small brain but the neurosurgeon said that it could not be the cause because it's too mild.
I tried 3 different meds, but none of them helped in any way. I felt like the doctors didn't think it was that serious.
Also I've never had a full blown panic attack since 3 years ago.
TBH I've hoped that I'd just fall unconscious one day at work, so the doctors would take me serious and examine me thoroughly. But it never happened.
Now everyday is a fight, constant muscle fasciculations, pressure in my head, floor is swaying, Brain fog, Chest pain, feels like ants run over the left side of my face, Body feels ten times heavier, Legs feel weak, muscle tremor when used.
It still seems to me like it all has a physical cause, and i don't know if im wrong.
I've tried yoga, walking everyday, i don't drink or smoke anymore, and i eat relatively clean.
And everytime I try to do sports i just get dizzy and my day is fucked. The internist said my heart is fine though..

I don't know if anyone else feels the same, I'm not that of an anxious person, i work as a waiter in a high class hotel and i didn't even break down once, even though everyday feels like hell. Also i am a dungeon master for a DnD group, and even though I get a little stage fright before a game, i will not have a panic attack. The thing is though nothing feels like fun anymore, i used to play guitar and make music, but I stopped because I couldn't concentrate anymore. I've also lost two of my best friends, because they wouldn't deal with my shit state and they still smoke weed on a daily basis.
I just want to live a little and enjoy anything again, but it won't go away.

So if anyone read that, i just wanted to ask if anyone of you felt the same and if it really is what the doctors say.
I thought that if maybe someone said that they felt the same, that's the push i need to get therapy.

Thank you.
