I am struggling with severe anxiety coupled with depression/depersonalization, emotional numbness, depression, etc coupled with brain fog. I have been lead to believe that my concentration problems are due to the anxiety but I'm not so sure (haven't been to a GP about this problem). Any time I try to think/concentrate/get to the full potential of my brain, I start feeling lightheaded and dizzy, like my blood pressure drops really low in my head and my ears start ringing. Any time I try to remember something or try to rationalize or just plainly try to get my executive function up and running, I'm bombarded with this problem like there is not enough blood in me to actually circle through my entire brain. It's really destroying my studying potential and I can never engulf myself into the subject because I literally do not have the ability to! When I tell this to my parents, they don't believe me (I've never been the lying type) and just think that I'm trying to give myself excuses. My symptoms also include some headaches of all types, mainly in the front of my head. Sometimes when I feel really tired I feel a little vertigo, like I'm pulled to one side.
My blood pressure is 100/60~110/70 and blood tests showed that everything was normal, hemoglobin was 141. I'm 19, ~1.90m. I'm trying to focus out all of the disabling anxiety and depression symptoms from this, but I don't really think it's from panic, since I'm trying to observe myself and I don't start hyperventilating like crazy. I feel more of a zap of pleasure during this, like my derealization and brain fog are starting to lift but the excitement is too much and I start fainting. This happens for around a second. One time I was trying REALLY HARD to concentrate on a test but I physically couldn't do it, I felt like I knew all the information, but I need the full capacity of my head to write it down and for it to be coherent. So I tried really hard into concentrating and my blood pressure dropped so low that I started to get really dizzy and started to see black around the edges of my vision and everything sounded like it was a mile away from me. I freaked out that I was going to faint in the middle of class and become a laughing stock in front of everybody and luckily that panic pumped my heart and brang me back into my semi-aware brain fog that I'm constantly in. Thus I become extremely depressed that nobody believes me and I may be stuck like this forever and at the same time not be able to actually do anything about it because it impairs me mentally.
All of this started after me trying a low dose of magic mushrooms (It has been the biggest mistake in my life, the cause of my debilitating anxiety and depression). Everywhere everyone said that shrooms are one of the safest things with which you can experiment with, and to an extent, I still agree, but this has just been unlucky for me.
The only logical reason I could find is that I depleted my serotonin, since that is all the symptoms matching (in a way). I do have terrible anxiety and being overwhelmed and abnormally low self-esteem, I do have mood swings and migraine type headaches, I do have GI issues, mainly constipation, and from what I've read, serotonin controls the cardiovascular system and more serotonin = higher blood pressure. And this is also causing migraine headaches, because the blood vessels in the brain open up and leading to the pain. Migraine medicine is based on serotonin alternation. Serotonin is also a neurotransmitter that plays a role in cognitive function and sends signals smoothly from one neuron to the other. It plays a role in memory formation and cognition and thus indirectly to attention deficit. This is the only logical explanation that I could think of. All my blood tests showed nothing serious. I have been on 5HTP (50mg morning and 50mg before bed) for the last 5 days after realising all of this and I do feel a bit of a improvement but it's too early to speculate. After 7 days of it, I'm going to be doubling my dose and see how it goes, since if this really is the root of my problem, I'm really deep into it to experience every single symptom, so I would really have to go heavy on the dose and not just be on the minimum maintenance does that is recommended. Well the most reasonable choice is actually to go to a professional, be it a neurologist or psychiatrist but I wasn't able due to the sheer amount of anxiety/stress being on my shoulders and the situation in life I am right now. I just wanted to post here because I wonder if I could get someone's opinion on this, since I've never heard anything like this in the entire Internet!
