Request that all sessions of this account are logged out

I think someone’s in my account. Pages keep saying I’ve seen replies even though I have not. Please log all sessions out if possible.

Changing your password will do that.

Ehh, after a certain amount of time not reading a thread with new responses, it marks itself as read on the recent tab.

I did that but it’s still happening.

You proabebly have a keylog on your computer then.

Get MalwareBytes then scan your computer, you are probably keylogged.
