I probably worried you enough in your other thread (in which i recommended a blood test for thyroid levels) but I meant to ask you if you were exerienced rapid weight loss ATM... because it's also a symptom of hyperthyroidism. So, yep, get your blood tested It was my second main concern (weight loss) when I saw my GP for my condition. Once again i'm not necessarily suggesting you have a problem with your thyroid... i certainly hope you don't! It's a shocking thing to have... but just for peace of mind stick with your plan of seeing your GP and getting a blood test done.
