Too much thinking is bad for your health

I've been feeling so exhausted for the past couple of weeks. Barely had had a decent sleep. Cant seem to make myself go to sleep. Every night, my head seems to just keep on churning and churning. Thinking, thinking, thinking. Curse you, brain! Too much thinking can restrict you from doing a lot of things! It can prevent you from just...living. Loosen up! But I cant seem to. Too scared, too allergic to risk.
