I will spare you the details, but what I described is a mere fraction of the dozens of things that arose pretty much solely from and were worsened solely by; my anxiety. In one downard spiral I can only described as having ended in the greatest terror and physical not just mental pain I have ever experienced. I came out of it a new person, not just because I had to question, reflect and change everything I knew about anxiety, my psychology and the mind but also because it was so intense I truly feel like it was the life event that has most acutely changed me. Because it broke me. BUT NONE OF IT MAY HAVE HAPPENED had I not had ignorances and a lack of insight beforehand. Part of what made it so vicious is the sensation that you are also experiencing; that there is no way this is anxiety, something more HAS to be happening. Guess what? Just anxiety, i've seen almost every single symptom all but vanish in the year since as I have learned to have a better relatonship with anxious thoughts and gained insight into how the human mind tends to function.
While my experience may sound scary it is actually exactly what you need to hear. I learned from my erroneous mode of thinking the hard way, but you can learn and benefit from it before the fact. I was never in any actual danger, and neither are you! :D But by engaging with anxious thoughts in a negative manner; by buying into the fear of uncertainty, by TRYING TO CONTROL and be aware of everything (which is what it feels like you should do but you SHOULD NOT) you are actually just amplifying the presence of anxiety in your mind, this consumes your working memory and attention in a progressively increasing manner when there isnt an actual threat and what you are afraid of is symptoms of the over-active danger-aversion mechanism we all have. Which is literally fuelling itself. The more your attention is consumed with fear and trying to control said fear (particularly) the more sensitive you will be. This hypersensitivity will lead you to notice "more problems", will make you feel more overall unsteady and crucially will neurologically increase your overall neural stimulation (literally). If each of your senses are in a state of hightened activity (induced by powerful anxiety) this can literally make random/non-meaningful neural activity surpass your perceptual threshold and hence; your perceptual disturbances.
You need to do some acceptance work first and foremost; of truths you deep down know to be true. A) Almost NOTHING in life is in our total control, and you will notice that anxiety revolves around seeking irrational levels of control (like being uncomfortable with the possibility of getting shitty or no sleep, which happens to everyone), B ) You feel like you are in danger but it is probable that there is literally nothing to be truly afraid of. And finally that you have a poor reaction to anxious thoughts/fears and have a tendency to get involved in trying to "solve" everything that while it feels like the right thing to do (and is commonly the innate response ironically) is actually detrimental.
Now you dont need to do any more thinking about those things/rationalisation, youve logically prossesed them. So now the anxiety; when it arises or when any of your symptoms arise you need to be Mindful, a technique which takes a bit of time and practice but the jey is that it is effortless. Unlike engaging with anxious thoughts (putting cognitive effort in) you want to let the thoughts, feelings and sensations come and go. You need to let them be, because they really arent your enemy, they sre a part of you, they ARE you in a sense. Not only is there no point in resisting/avoiding/checking against them/fighting them but it is acrually very detrimental. Let yourself feel the feelings that arise, notice the thoughts, but you need not be afraid of them, they dont have to define you, everyone has irrational psychological elements whether or not they admit it. Its okay. I really recommend Mindfulness, particularly a free app called Headspace that teaches it to you as meditation, but not spiritual, entirely a psychological approach. And its awesome, very relaxing as well.
Man I could keep on talking about this, I have learned a lot in the last year and have integrated it with my Neuroscience studies, but I cant understate how safe you are and how hard anxiety can turn against you I was in my third year of my Science degree and I was still overwhelmed and crushed by my lack of insight. If youd like to know more or have any questions ask away as I could keep going for far more than one text response would allow haha.
. I had a pretty decent sleep tonight, but wow the headpressure i have now and pressure on my jaws is crazy
