OK kinda seeking advice kinda ranting. I apologize that this will be a sorta long post ahead of time.

I do know that a lot of stress has a negitive effect on the mind and body, but however is it normal for my hair to be falling out somewhat? OK currently I am taking care of my grandpa who has terminal liver cancer that metzed from his esphogeal cancer. This is really the major stressor, but other than that I'm a senior in high school with a somewhat tough schedule of 2 ap classes and some difficult (for me) courses. I am aware that since I am a boy of fall taking my helmet on and off does break my hair, but normally i can run my hands through my hair and pick out oh id say 6 or 7 hairs that are shedding, but lately its normally about every 5 or 6 days ill do that and get 20 or 30. I am extremely stressed out as my grandpa is more or less a dad to me than anybody and always been really close. I constantly feel like I am going to lose my mind as nobody really asks how I am and I am actually having to leave school on an average of about once a month to go get grandpa for some reason or other, most reccently as of last tuesday he had fallen down. This has been going on for a year or so, he is a former diabetic, he was never out of shape really, he developed diabetes when he had a stroke 5 or 6 years ago. Yeah i got a couple of buddies and one close friend but they are just buddies and my friend and i are drifting apart slowly. Is it just me? Am I stressing myself out even more or what? If it makes any difference I am also pushing myself to get my short story finished and published before i graduate.
