So sick of hearing it

I've had nausea for about 2 weeks this week it has really slowed me down I eat crackers all day and I've only been able to eat once a day. I'm 6 weeks on Saturday and my mother in law and others keep saying I'm lying or I'm "milking it" that I'm a hypochondriac and I'm not really nauseous because it's "too early". It makes me want to punch them in the throat! I've had headaches daily because everytime I try to eat in the morning I have to spit it out and can't even get it down. I've changed to taking my vitamins mid day - night and I started on b6 but I still feel like hell but they are only making it worse. My mom has been super supportive and my stepmom said she started throwing up at 4 weeks everyday through her whole pregnancy yet my inlaw and her bf's family keeps putting me down. I know the b*tch hates me but damn why can't she leave me alone?! Especially since she wants nothing to do with her grandchild!
