So, I'd go home at night and fill up my journals about how miserable I was and frustrated. Then I'd eat my anxiety. That's where I learned that habit.

What does "eat my anxiety" mean, please? My best guess is to eat a lot to offset anxiety, but it doesn't sit well somehow because the words "eating anxiety" sounds more like "enduring" anxiety to me.

However, here is another possibility: The expression "eat my anxiety" is very close to "swallow my anxiety" which would be a common expression. I haven't actually heard "swallow my anxiety" but I've certainly heard "swallow my fear," "swallow my anger," "swallow my objections," etc. "Swallow my anxiety" would mean "push my feelings of anxiety deep down inside myself so I can ignore them." This behavior could also lead to the development of an eating disorder.

As I said, I think your guess is correct, but if your meaning doesn't seem to work in context, consider this alternative.

By the way, it would have saved you a lot of confusion if the writer had written "...and then I'd eat my anxiety away."

> "swallow my anxiety"

Yes! That's what I wanted to mean by "enduring." I really don't know which the author meant since the other part of the text didn't have anything to do with it.
