What's wrong with me?

I feel awful. I haven't felt this way in months. I have no energy and very little motivation to get up and do anything. And my pms was worse this month than it has been in months.

Ever since my doctor found the maximum thyroid dose I can take safely, and then added anti-depressant to it, and adjusted the dose a bit, my pms has been MUCH better. Then I cut sugar and potatoes out of my diet, and drastically reduced white flour. That increased my energy and motivation tremendously. Now all of a sudden all of that is gone. And I can't figure out why.

I'm still taking my thyroid and anti-depressant. And as far as I know, I'm still not eating sugar, potatoes, or much white flour. Although, I have been eating some no-sugar-added ice cream, which may have some stuff in it that could be hurting me. I think I'll put what's left of it in the deep freeze and see if I start feeling better. I may also go ahead and cut white flour completely out of my diet. I know it's hurting me. I just thought that eating it in such small amounts wouldn't hurt me too much. And it didn't for months. So why it would be now, I don't know. I've got to figure this out. I hate feeling this way.
