Am I Too Old?

I am a 59 yo female. I've only been picking my skin about 1 year. I've read online that skin picking disorder starts by age 45. So do I really have it or is it some other reason.?

I pick at little tiny black spots and white bumps on my arms and the backs of my hands.

I pick all the scabs in the morning and off and on through out the day.

I examine my hands and arms when I'm in good lighting to look for new "spots". If I see any, I immediatly pick them.

I've on a few occasions picked scabs in the dark.

If there is much bleeding I wipe it with a finger wettened in my moutg.

I feel embarrassed in public places but I live in area where the daytime temp makes it impossible for me to wear long sleeves. Still, I don't stay home.
