Hi everyone, just an update and last post from me so it'll be a long one! 
It's been almost 4.5years since my bad trip and I definitely still have anxiety and all the other stuff I posted earlier (weird vision, floaters, feeling distant). I've definitely become used to it and still try to live life like normal.
Some days are harder and more uncomfortable than others, some days I make it worse by drinking coffee or getting drunk as **** lol.. but I try to live life as normal as possible. (Again I don't recommend drinking or smoking anything because it will most likely exacerbate everything.. took me 4 years to get the courage to drink again after I developed this lol).
As I mentioned in my previous post you have to trust me that you won't go crazy! (But definitely put that joint down and take a break if you can do safely because the mind is very fragile...hence why you're here in the first place)..
Just know that crazy people don't know they're crazy so if you're here looking to figure out what the hell is going on that's a pretty good sign you're okay! Haha
If you do feel like you're going crazy it's because anxiety is a motherfu*** and will make you feel like you're not in control.
It's a constant battle but overtime you'll own it, just like a few other people on here have commented- you'll overcome fears and things will slowly but surely get easier and more normal.
Having anxiety is not just feeling"nervous, or shy at times" like people post on Facebook/insta etc...
Having anxiety is a constant battle with your mind, a mix of uncomfortable body sensations, stomach crunching fear, confusion etc..
I saw a few (ok a lot) of healthcare professionals who confirm is just anxiety.. in my case I probably had it before the bad trip..made it 100x worse after smoking the devil's lettuce haha. Rip..
Some people are lucky and they just have a few days/months of this bull (and hopefully that's you!)
But for some of us like me unfortunately, it'll be a constant battle with some days being harder than others. It definitely gets better over time and who knows maybe in a few years time it'll keep getting better.
The derealization (which is the bit where you feel like everything is a dream.. detached, spaced out feeling) is a symptom of anxiety and other disorders. If you have no hallucinations (audible/visual) it's most likely just anxiety.
Cannabis can trigger (awaken) pre-existential mental illnesses like anxiety and depression and I think the best thing to do is to go see a professional.. even talking about it (like on here) makes you feel less crazy and not alone.
Last thing I wanted to do is list things that can help you right now. Like right now.
-1) STOP taking substances that affect your cognition (drugs, alcohol even cigarettes). A glass of wine probably won't kill ya but honestly... Why risk making it worse?
-2) If you can't stop smoking weed, cant quit cold turkey and/or have tried in the past but quitting made you feel worse then please see a healthcare professional. They can often provide support/medication to help you come off weed. And it's 100% confidential.
-3) Go see a general doctor (for a general check-up as they suck at mental health stuff) and get your thyroid checked, your bloods checked (check for iron deficiency anemia, vitamin B12 deficiency, etc). Deficiencies, imbalances, thyroid problems can mimick the symptoms of anxiety and/or heighten them.
-4) Once you've had a general check-up then go see a mental health professional such as a councellor, a psychologist anyone who has experience and a personality that you can work with. They work for you and should suit your needs, they should listen with respect and kindness. if you're lucky you may find a psychologist who was once in the same boat as you but was able to overcome it and guide you in the same direction.
-5) Stick to seeing someone as talking about your symptoms/sensations helps to normalize what you're experiencing.. helping you to overcome it.
-6) Excercise and review your diet (what I'm trying now). Excercising is basically like doing drugs.. but your own body makes them for ya lol (endorphins, dopamine and serotonin) same sht that prescribed medication such as SSRIS help increase/balance. (If you're on prescribed medications don't substitute/stop them unless you've discussed it with your doc).
-7)If you have been prescribed medications to manage this take it as directed but give it time. It usually takes about 2 weeks to start seeing/feeling changes. If you're afraid to take meds like SSRIs then remember that tried you tried weed.. (which had the potential to change your brain chemistry negatively) then why should trying medications that are meant to help be scarier?
(Now this one I'm a bit biased because I'm still too scared to try anything but leaning towards trying it especially for the harder days... Definetly giving myself some advice here lol).
-8) Review your life. Cut out stressful people, environments, situations if you can.. now it's about you..
In my case my energy is very limited now so I don't have time for stressful draining people or events.. You come first now- your health is priority.
9) Write down your sensations, triggers, what makes it better what doesn't to keep ttack
