Balding primarily on my left side?

[Fochapiv]

Hello,

I am 24 years old and have always had thin hair. I decided to take a picture of the side of my head today and it made me sick to my stomach. No one has ever mentioned that I have thinning, and actually get compliments on my hair quite frequently. There's really no family history of baldness. Please check pictures. It's now all I can think about.

Thank you
