I swear there is nothing left in me

Well I am 12 1/2 weeks along. I offically vomit every single thing. Food, liquid and pills. I keep nothing down. Doctor was concerned since I wasn't getting my meds in that I should have B-6 shots 2x/week @ $10 a peice. Plus supositories 2x/day. Well thats not working. Plus I am not sleeping. Ok I know I asked for it, I wanted to get pregnant. But holy crap I havn't met anyone with these kind of issues. So I am complaining today. I am exsauted and dizzy from no sleep ( I can understand no sleep), no nutrition, and no Thyroids meds in me. Thats all I need now is for my Thyroid to have problems and it to affect the baby. I know, just thank my Lord for giving me this little miracle. I do I really do. Well I need to go and get to work. Oh please help me get through this shift with out vomiting.!!!
