Fibromyalgia???

I wanna know how old you are and how old where you when you discovered you had fibromyalgia. My mom and grandma have it and I’m showing ‘symptoms’ and I really hope my body is just on some crack. I’ve only seen fibromyalgia amongst older people and I’m only 16, if you have it how do you deal with it on the daily? I don’t know how my mom does it...I just really don’t want it but if I do end up having it I wanna know there’s people amongst my age with it. I haven’t done too much research on it because it stresses me out thinking about it so sorry if I sound dumb, much love <333
