Expanding my knowledge but......

Hello everyone....
im expanding my search on trying to feel better. I was dignosed with hypotyroidism a year ago and was placed on levoxyl.
I noticed a slow change but i still dont feel myself tho my last
tests came back normal. I stay cold, tired and useless. Have long
spells of Depression for no obvious reasons. My most problem - i
forget the smallest thing!!! Im a college student and i am struggling to stay ahead- i used to not have this much problems with remembering and focusing on things. i just feel real sluggish. I have recently changed doctors - i believe this one is going to better. I am still learning as i go - i just now found out i cant have soy with my meds.
Something no one has told me! Pretty much i feel lost ...... i
honestly dont know much about this disease - and im hoping that
learning i can find a reason why i feel so bad now..... ANY tips
advice .... anything would be helpfull! Also one question i have to
ask is ive heard people talking about various thyroid meds.... armor, sythroid, so forth..... what is the difference in all these and what im on? does levoxyl have side effects? thanks and sorry for babbling!
I Hope :)
