Over the past ~6 months i've noticed that some hair has been finer than usual (the diameter was smaller and it had less color). This didn't really concern me.

When i went to get a haircut ~2 months ago, i noticed that a certain spot on my crown was kind of thin, naturally this caused me a lot of anxiety. I began to be hyper vigilant about my hair, noticing that some of the hairs that shed were thinner than others and were not as strong, as well as finding some very very light thin hairs.

In the past month i started to notice that im shedding way more than normal, up to 70 hairs in the shower and ~20 any time i would brush or ruffle up my hair for about 20 or 30 seconds.

I did research, and male pattern baldness seems to fit the bill.

As for family history, my dad started balding when he was about 35, my moms father when he was almost 50.

In addition to this, i was in a state of extreme stress for the entire month of may and half of june due to finals. In addition to the stress put on me by finals, i have an anxiety disorder an am very worried about being an adult, going to college, and the transition from childhood to adulthood. My dad thinks that if there is hairloss, that it is most likely due to stress, or that i'm simply projecting my anxieties about the future onto my hair and manufacturing a problem where there isn't one.

It could be hair thinning due to stress (hair is known to shed 2-4 months after a traumatic or stressful event/period)

Im planning on seeing a dermatologist in the near future (next several weeks) to get a more informed opinion.

and yes, i know that i do still have a thick head of hair, my concern is that it is thinning. My hopes are that maybe if it is MPB, i can catch is pretty early in the game
