Crazy is such a relative term. What exactly IS crazy? Why is it so bad to be this way?

At any rate, you're just fine the way you are. You are just going through and dealing with quite a lot right now and that can send anyone into deep waves of self doubt. Why not try to do some self care? Take a nice long bubble bath, do something you really enjoy like arts and crafts, working with your hands in some way, or stimulating your mind with puzzles and brainteasers. Do that and you'll feel better in no time!
