Is "you are yourself" grammatically correct?

I know what "be yourself" means. I usually see people using it in some sentences like "You have to be yourself", "You must be yourself" etc., but I barely see anyone saying "You are yourself".

Is that sentence correct? I used it in this below context when I tried to define what a friend is

"Friend is someone you have a bond with. You feel comfortable and are yourself when you are with them."

If it is wrong, how could I correct it, particularly in the context?


If you follow the entry of "be oneself" from Oxford Living Dictionary https://en.oxforddictionaries.com/definition/be_oneself,

you can define "friend" like this:

"A friend is someone you have a bond with. You feel comfortable and act naturally, according to your character and instincts when you are with them".

As about saying "You are yourself", I can give you some examples from https://context.reverso.net:

  • I see from your letter that you are yourself the daughter of a country parson.
  • You are yourself again.
  • See...? You are yourself again.

"Friend is someone you have a bond with. You feel comfortable and are yourself when you are with them."

I would say "and you can be yourself"
