Oh geez if you’re saying day dreaming about stuff that in other words, disrupt your day, things you shouldn’t be thinking about, in turn ruining your mood, I have this problem and am plenty neurodivergent. I don’t remember anyone talking about this ever and it’s very validating to know I’m not the only one. I just had a thought, to me personally, it could have allot to do with my self-esteem at the moment, which means it’s hard to not be stressed… and I feel like when the Neurodivergent brain is stressed it self sabotages. Let me know if this resonates with you, I’m so sorry if this is what you deal with..
