I don't know what I look like

I like how I look in the mirror mostly but when it comes to the back camera or “inverted” ones I genuinely freak out. I don't know what I look like anymore, not to mention the fact that I'm worried I am a catfish.

I am currently dating someone long-distance and would love to meet them face to face but the thought of me looking completely different and them feeling lied to is eating me up inside.
