Hello, Idontevenknow64.
What is it you want to know? I can tell you for a fact that these thought processes are possibly the most common of existential obsessions and i probably see this exact same obsession on here once per week. I went through a matrix phase myself back in '14/'15 and suffered solipsism which cleared up after a little while.
The reason why we get these thoughts is because when were anxious and dpd, the brain generates wierd perspectives on reality to which there are no answers to. The anxious mind doesnt have tolerence for uncertainty. I mean the sheer scope of potential questioning is literally limitless, and you're now veiwing your life through the lense of this existential question because they tend to come along like a freight train and stick in your head. When we're dpd, these thoughts seem very real and i lnow how difficult it is to separate it from reality.
Best advice i can give is to be an 'outside observer' and to start viewing these obsessions as simple thought forms randomly generated by the brain. The thing is, it's not actually YOU thats interested in this line of questioning, it's the brain thats doing it outside of your control. So let the thoughts come in and fly out without interracting. Then they'll diminish.
Also, no more weed
