First, hang in there. You're going to be fine and it will all work out for you for the better.
Please consider throttling back your intake - it's overwhelming both your body and your psyche. Everyone has their thresholds and you need to find out where yours is. Don't do more than you can handle. First and foremost you have to take care of yourself. We're pulling for you to come through.
What's happening is all that junk is coming out and your body is being forced to dump it any way it can. Something that might help in addition to salt loading is chlorella. I take that every day and what it does is bind to the bad metals and carry them out. Another is to drink distilled water, which also like to suck out bad metals.
Ultimately, whatever you decide to do, hang in there and do whatever you need to do to keep it together. The purpose of detox is to make your life better. If it's too much, step away from it, regroup and get back to where you feel better about yourself, then start again, only more slowly. You've got a lot of toxins in you and the good news is that Iodine therapy is working for you, you just need to take it a little more slowly.
Hang in there, Trysten. I'm rooting for you. You'll be okay. Post regularly so when know you're still okay.
