Oral Fixation.
I think I might have figured it out, but to admit it, I have to come out with a truth I never admitted to anyone outside of my family.
My mother never breast fed me, which (not given a proper outlet for my Oral psychosexual phase) gave me the habit of sucking my thumb. I was never told not to suck my thumb when I was a baby and actually held the habit until forced to get braces…when I was 13.
When I was quickly tossed of my habit, a habit I’ve had for still most of my life, I’d chew on things like straws and pens to get any kind of fix. But of course, that wasn’t enough, and food replaced it. Food is crunchy, food is soft, food has unique tastes that my thumb and straws didn’t have.
I became so big because I was denied being breast fed.
