Thanks for the encouraging words, everyone. They really have helped and they mean a lot to me.
It's strange. I sometimes can go a few days where one of the withdrawal symptoms calms down or completely goes away. And then, just when I think I might actually be getting better, the symptoms return again...with a vengeance.
Some have mentioned in this thread that I should see a doctor. That isn't an option for me. I can no longer afford health insurance thanks to Obamacare. I'm not trying to make a political statement by saying that. It's just that...it is what it is. I used to carry my own policy, but it's now so expensive that I can't afford it anymore.
