Overwhelming anxiety from minor everyday events

It's so frustrating how a tiny, normal thing, like my cat giving me a little scratch, can completely send my anxiety spiraling into a full-blown panic attack. Even when I know logically it's irrational, my mind just latches onto the worst-case scenario, making it impossible to calm down. It feels like my brain just won't let go of these terrifying 'what if' thoughts, especially with my OCD.
