Fake it till you make it.

If you want to stop over thinking, then just stop thinking about it.

Just pretend that it's all nothing.

One day, when you care less, you won't feel a thing.

There are things that don't need attention. So, don't waste your time on that. Eventually, you'll get numb. 

I know people say numb is not good, but for some people, numb is what gets them going.

Because being able to feel is just too much for them.

I don't see any harm in faking things to make life easier for you. People don't become great liars in one day. Eventually, you'll learn to lie to yourself. And no one would ever know.
