I think addiction to ANYTHING is real. I mean hoarding things isn't a drug but it is an addiction. I have believed for a long time that I am addicted to food. It's embarrassing to say that, but when I was a kid, I would get really stressed and cry if something I wanted to eat wasn't in the house, and my parents would get mad at me thinking I was just acting spoiled. I even thought that. But even now I get antsy, tear up, feel anxious if I can't find something to eat that I've set my mind on eating, or if someone changes their mind on what we were going to eat and I've been set on eating that one certain thing and looking forward to it. I also usually eat under stress if I am upset, sad, angry. The same way people do things like marijuana or smoke cigarettes to calm them when they are stressed. It's just automatic and I don't even think about it. However it's possible that its more of an anxiety based thing in my case than an addiction because I have recently (unofficially) discovered that I have some level of anxiety and a lot of it has to do with me setting my mind on something and having last second changes or alterations to what my "ideal" would have been. It's gotten MUCH worse recently due to certain things happening, and I've finally identified that within myself and by doing so I've realized that its something I believe I've dealt with my whole life and just had no clue what it was.
