We end up convincing ourselves our concepts because we get trapped in circular thinking.
If you question that the world is fake, you'll obsess over an answer to disprove that; finding that answer, you'll find a way to circumvent to test the integrity of said answer; and so on and so forth. When we think this way, we oftentimes avoid how inaccurate and irrational our thought processes really are. I believed that the world was fake as well and I found myself dwelling over it for hours in the day. What I wasn't taking into account was that I spent far too much time trying to find answers to a problem that my brain would never allow me to solve. Two years worth of time!
I met with two different psychologists at the time. After telling them both about my experience, they told me to try something for just a week. Every time I felt like my thoughts were getting the best of me, I would audibly tell myself to stop and would force myself to focus on another thing. I'd watch a YouTube video, write in a journal about something, or play a game. Alongside this, I would allot fifteen minutes of my time in the evening. In these fifteen minutes, I'd let my brain do whatever it wanted. Think about the world being fake, answer questions and question answers, et cetera. After those fifteen minutes, I would force myself to move on completely.
In my experience, this was actually the most beneficial thing I've ever tried. It wasn't exactly easy, but your brain has a way of rewiring itself over habits. If you make it a habit to actively shut down these thoughts throughout the day and only think about them in the allotted time, your brain will catch up and make it an almost natural process. Again, it's not incredibly easy at the start. There were plenty of times where I failed and fell back into my obsessive thought processes, but I'd pick it right back up and try again. I'd give this a shot if I were you! It really helped me out so maybe it can for you as well.
And Google doesn't help. I keep reading about delusional disorders where people do not believe the world is real. I feel like I'm on my way there.
I wouldn't use Google at all, haha. It'll only make your thoughts worse and you won't find any answer that'll help you immediately. As for the delusional thinking, there are plenty of people that have philosophical obsessions like the world being fake. Anxiety tends to do that to people! Which is far more common than an actual, substantiated delusional disorder. Thought the same thing myself. In fact, I thought I was developing schizophrenia. But in actuality, it was just my anxiety and obsession taking a hold of me. It happens to the best of us.
I hope things get better for you, though. It must be rough balancing being a mother with these thoughts! :c
