The problem is often that there are compounding issues. There's nothing that stops you from having TIA at the same time. People often describe being overworked and stressed as burning the candle from both ends. Hypomania can more aptly be described as setting the entire thing on fire.
My post wasn't meant as some form of medical diagnosis, more of an observation from someone that lives with this. The feeling of numbness and having some sort of brain fog is how a lot of people with mood disorders like ADHD and bipolar disorder would describe things.
