Bummer-ish/Good-ish

Monday I had my annual physical with blood work and that showed that my thyroid is under active.
I'm having a lot of mixed emotions right now. I'm super relieved, because I honestly was expecting something a lot worse... but at the same time I'm a little shocked! I mean, I never would have in a million year guessed that it was my thyroid that was making me feel lousy.
I've been feeling kind of punk for quite some time now (over two years), but one of these can't quite-put-my-finger-on-what-isn't-feeling-good kind of punk, so I thought it may have been mental and just kept fighting it. Honestly, when I was pregnant, I felt the most well, because I was getting some help from Sean's thyroid.
This may not make a whole lot of sense, but now that I know what is wrong, I feel like I can give myself permission to feel kind of punk. I know that it's something I can't fight and I have a huge weight off my shoulders knowing it's not mental. I feel like... I'm not really sure.
I've been prescribed medication to correct the low levels and have to go back to have the levels checked in six weeks. I'm actually looking forward to it.
I'm looking forward to feeling well again...
