Over working myself during a workout at Tae-Kwon-Do, had to go to hospital because I couldn't breathe properly, heart was beating way too fast, my muscles were shaking, and that was the first serious workout I done in 6 months.

You have to give your body time before you can shift back into typical training sessions after a long break. I do karate at my uni and everyone is so unfit after the summer holidays because, let's face it, everyone's going out and celebrating Christmas and New Year, rather than working out, lol. The instructors know this and make the first few training sessions a little less demanding, but you should also know when you're pushing your body beyond its limits. After all, you can't train as well with a broken body.
