Is it bad to think too much of everything?

If you want to get out of your head, get into your body. Pay attention to your senses. Focus on what you feel, smell, taste, hear, and see. Breathe. Remind yourself that this moment is more precious than any other moment you may be creating in your head, and that you will handle life's problems when they come.

When you're not okay, it's better to do relaxing things. You should try mindful meditation and excercices.

Think nice thoughts btw are you asian?

The cure is rather permanent, so I don't recommend it.
