Is it normal for your mind to get "tired" over obsessing with something 24/7? My recent obsession has been my worst yet and it's Existential OCD. Everything I do or every time I feel happy an intrusive thought comes into my head saying "this doesn't matter, you're going to die so it's all pointless" or simple "what's the point?" Thoughts come into my head but I hate them. But lately I've been getting bored of obsessing about it? And it's making me worried that the thoughts aren't causing as much distress and depression as they used to (which was last week) is this normal? Because I obsessed about it 24/7 and what triggered it was my philosophy class we studied about Nihilism and it scared me that most philosophers are depressed their whole lives. But yeah is it normal for my mind to just start getting tired of the obsessions and become desensitized? I'm starting to get worried that I'm subconsciously becoming nihilistic:((
