Nervous

Er

I'm about to buy my first adult item. I'm scared to death? My 18 and 13 year old brothers live with me and since I'm mostly blind, my mom usually goes to get my mail. I don't want anyone to open it. Where can I hide it?, at 22 I have never bought anything online on my own before, What if someone does open it or find it? That could ruin my reputation. Should I back out now? What if my dad finds out? I'm freaking out, help!
