calm down dude
BL is not an emergency help board and what's more posting a bunch of panicked shit isn't going to do you any good. sit down and take some deep breaths.
also, stop taking huge doses of ghb or mxe if you keep getting symptoms like this. GHB has a tendency to make you feel like you're gonna die if you push the dosage or potentiate it too much, doesn't mean you'll die.
If they kicked you out of the hospital it's a good sign, it means they think you're healthy enough and just wasting their time. Maybe the doctors, who make a living by doing such things as judging people's health, know better than someone all loaded on sense-distorting drugs?
