Thyroid up, thyroid down, thyroid up?

Well, I don't know what's going on with me lately.  In the last week, I've felt like I did when my thyroid was overactive, now it feels normal again.  Can your thyroid go overactive, under-active and then back to overactive?  I went for a blood test but it came back normal.  It's just been crazy.  I guess I just need to wait and see what happens.  Could all of this be related to stress which I've had a lot of?  Bills seem to pile up and never go away no matter how much I try to pay things down.  And J keeps complaining about his job and it's starting to upset me lately.  He's the only one who can change that and he seems scared to move forward.  Now he tells me he should have sent out his resume last year because he could have gotten a job last year with a major.  Now he's not so sure.  The whole thing just irritates me.  Here I am trying to save money and getting nowhere.  I really hope we can qualify for a loan next January.  I really want to go for another fertility treatment by then.  I just thought we'd have more money saved and our credit cards paid down.  J just doesn't make enough money and it's hurting us.  Anyway, we did get to visit family over the 4th of July.  J's nephew got married. It was so nice to see everyone and as always, it was too short of a trip but I'm glad we went.  It's the little things that keep me going.
