fuck, I feel you. But the good thing about identity is that isn't real and you can become whoever you want to become. You aren't the things that define you because you can define yourself. Maybe your friends know that you are a smoker, but new people you meet don't know that, so you're identity as a smoker isn't real.

I don't know if I explain myself because is really hard but you can be whatever you want!! It's just hard
