Trying to sleep it off, going to work next day does speak to an insane work ethic/sense of duty, or perhaps fear, fear of losing you job etc.
In any case, I wouldn't have gone anywhere, I would have called an ambulance even if they insisted I take myself to hospital, like they sometimes do, I would have made something up. I'm like, I paid taxes all my life, now you pay me back! Lol.
Hope yoy get the help you need Mike, and within reasonable time.
Often in healthcare "they" talk about the need of "demanding" help to actually get help. Some people like myself aren't good at that so often don't get help. And if rich maybe having a lawyer with you to the hospital would be a good idea, I'm not sure, but I think a lot of people die out of pure negligence and not giving a fuck, other priorities.
