Where to go from here?

[fuzzbucket]

Hey, 19 years old and new to the forum. Noticed I have been shedding for a while, and although I have always had a high hairline it has definitely receded.
One picture shows hair parted in middle to display hair density (or lack thereof). I have always had thin hair but I think now thinner.

Just looking for an outside perspective on my stage of hair loss, what I should expect in the near future, what to do (drugs or haircut), etc.

Any comments are appreciated- I'm new to this balding thing but probably in it for the long haul! Thanks
