Is my hairline receding?

[User3333]

Hi there,
I am a 17 year old male and I think my hairline may be receding. None of the males in my family went bald before 40. I have always had very thin hair. There has been fairly significant thinning in the crown region. This past year I have been to the gym fairly regularly. I have dealt with depression which has led to some stress in the past. Could someone tell me if my hairline is receding please, and if so what I should do from here?
