Thinning maybe at teenage years Please help

Hey guys Its been a while since I cared for my hair since I was a child but when i got to 14 I lost so much of hair like I would shake my head and loose 3-4 hair everytime and then it stopped when I got to 16. Ever since than its been an year that I dont have even a bit of hair loss but I think I am balding maybe since the hairline looks awful and maybe the temples are bad also I dont have the same volume I used to have back then in the years. Guys please tell me if this is me balding because its just putting phenomenal stress on me.
Also I can hide this shitty hairline with any haircut but its awful I want to know its maturing hairline or its receeding.
