That does have me worried. I really hope that's not the case, but reading all this makes me think that it might. I'll be seeing my doctor about hypothyroidism next week.
Thanks you all for your helpful messages and insight. Though all your theories vary, I will be following your advise and see where it gets me. But first I'd like to have this crossed off my list (or have it proven, but then atleast I know what it is that's causing me all these problems.)
I will keep you all posted on how things are working out and who turned out to be right ;-)
