Creating profile in a single page (user's own profile and public view of someone's profile)

Hello, I'm trying to build a social media app,

I've got profile page in the nav bar and if I, as a user try to view someone's profile, it gets selected in the nav bar as if it's user's own profile. How can I fix this, not making any action on the nav bar while user tries viewing other profiles?

Or should I just use 2 pages, one for user's own profile and second to view other's profiles. If so, what would be the disadvantages of doing it this way?

Thanks!
