It's not your place to try to crush another person's dreams. I hope you don't treat other people like that in real life.
Goober: DON'T GIVE UP. Keep trying. If you dedicate yourself, you can do it. It will just take longer for you than some other people, but in the end, once you get there, none of that matters.
There are other careers in the world besides anesthesia that can make you happy. They just might be harder to identify. It never hurts to talk to people you respect in other industries (in real life) and look into other options.
Either way, unfortunately, a worthwhile career takes many years of planning and hard work to get that coveted first job.
Don't let some jackass on the internet influence your goals.
Hang in there.
