When does it get better?

I swear I feel like I am dieing slowly... Im still really sick... I haven't gained a single pound ( however my belly has gotten bigger)  I have bad headaches and in general I feel weak and just plain sick.. I try to eat. I eat baby carrots every day because I can keep it down and blueberry bagels but Im at my ropes end.. I can't function period. Most days I can't even get out of my house because I feel so sick. I havent been able to go to work because when I go I get dizzy and some of the times I throw up. My doc knows all this and he said its all a part of being pregnant. ARGH!!! Im just so darn frustrated... I just want to feel normal... Sorry its a bad day for me.
