My genetics are making me miserable

I just turned 25 several weeks ago, and I just became aware that I'm losing my hair (male pattern baldness)...I feel like an old man already and I still have 50+ years in this world (give or take)!

I always assumed as I got older things would start to go wrong, but at 25 I feel like this is way too early for me to be losing my hair...it's making me extremely miserable, especially the fact that no one in my family ever mentioned it to me and it's supposedly been happening over the last few years, which made me think maybe it's work/stress related, but maybe that's just me being in denial of my own genetics...my mother's father was a victim of MPB, and that's usually who you inherit it from.

Is anyone else in the same boat? How do you cope with getting older/things not going your way? This situation is making me extremely depressed and I can't seem get passed it
