Receding heavily at 18[Advice needed]

[thebalding18yearold]

Hey everyone, so I finally plucked up the courage to make this post after about 8 months of being afraid to so it all began when I noticed my hair was thinner about September 2015 and as I inspected further I realised I was actually receding. I had long hair before and I actually got my hair cut quite short on my birthday at August the 13th and I didn't notice anything. but here I am about 8 months later heavily receded with no sign in stopping. I'm not denying the fact I'm balding, I just don't know what to do. Can I even stop it? is medication worth taking. Oh and My mothers father was balding in his early 20's, my father is bald but his father has hair and he's in his 80's. My confidence is in the gutter and I am now paranoid because I know how bad my hair looks, I really need some advice thanks. Lastly here are the pictures. p.s sorry for the shirtless pictures
