I feel like such a burden

Because of my pregnancy symptoms, I've been missing a lot of work. I'm 13 weeks and sometimes my morning sickness/headaches put me completely out of commission. I work from home so every time I call out I feel like such a failure and a burden on my husband. I do have FMLA so the time out is covered but not paid for. We're losing a ton of money and I'm still feeling so sick. I'm fighting to stay on this shift now. Hope next trimester is better...
