Feel like I can’t work - Help!

I’m only 6w5d today but I’ve been so consistently nauseous, fatigued, and achey since 4 weeks. I’ve vomited several times and I’m beginning to feel like I just can’t work anymore. I’m not sure if I just need to vent or if anyone has any valuable advice to give me I would please hear it. This is my first pregnancy and I’m positively miserable- I can hardly get out of bed, I can’t do chores, I can hardly even get myself to go outside for a walk. I feel SO exhausted and SO consistently nauseous. I don’t want to even plan things with friends or family for fear that I won’t feel up to it/I’ll be sick. I simply don’t know how I will continue to go to work. I only work 3 days a week and a few months ago I used to work full time and be the primary source of income for my husband and I. I’m feeling really lousy for not being the motivated energetic person I was before but I just can’t do it. If you have had a really rough first trimester how did you survive it? I’m not sure if we would be okay financially if I stopped working, my husband is in sales and his income is inconsistent so some months he makes a lot and others not so much. I don’t know what to do. Please offer any advice. I love this baby and I’m grateful for this pregnancy but I just feel miserable.
