13+4 and my morning sickness/queeziness, fatigue and faintness is absolutley killing me. I cant work. I cant keep up with houshold duties. This has been continuing to get worse from 6weeks. I sleep 14 - 16 hours per day cause its the only way I get any relief. I have been researching and some say this should subside around 16wks and other research says it could last the hole pregnanacy and i cant handle that financially or emotionally. Really struggling at this point.
