I've been on a shopping spree. Not in a good way...

Hi, first post. Also a bit of a confession. I've been stealing now for about a year. Haven't gotten caught. I've been stealing stupid shit. Food, clothes, things I can easily afford. But I've also stolen things I didn't need. So now I'm on a bit of a profit. Thanks to my grandma's basement. So for the past few months, I've been making a profit off of my "steals". Haven't been caught, and I feel like I can steal the Mona Lisa if I wanted too. I'm excited, not in a good way. I'm on edge all the time. I feel like I can't lose. Like I'm unstoppable. But I feel constantly sick. I get diarrhea whenever I steal. I've never gotten caught, but I'm so paranoid. Is anyone else feeling like this when they steal? Or is it just me?
