Feel like I'm gonna break..

Just need someone to vent to that'll maybe understand.. I'm 11 weeks and I've been sick (nauseous, throwing up) for nearly a month and a half now. I've been to the hospital once for dehydration and I'm just so sick. I prayed and prayed for this baby and I know I'm so lucky. I'm just not myself. I'm a very organized, energetic and clean woman. Before I got pregnant my home was never dirty or dusty and I cooked dinner almost every night. I know my fiancé doesn't mind most days, but I can't even get out of bed long enough to go the grocery store. I feel like I'm letting everyone around me down but I also feel like no one understands when I say how horrible I feel. I'm just very emotionally drained from how I feel physically.
