Yeah, I definitely empathize.
Another thing- I don't know what type you are, so ignore this if it isn't relevant, but it may help to mimic or produce a lot of Ti. I know that when I'm whiny or pouty, Ti can put me in a "yeah you're right I was dumb I will go do that now" mode. Blaze's suggestion about the book isn't a bad idea. If you do that, I would suggest somehow reinforcing the ideas in the book on your own, but somehow trying to frame them in a Ti and not Te way, like "this is what these food groups do and they will have this effect on your body" not "if you want to feel better you need to do this."
