Sick all day everyday

I am 24 six weeks pregnant with my second baby. With my first the sickness started around 9weeks and continued until I was about 32 weeks. It got so bad I was put on bed rest at three months. With this one I found out I was pregnant around 3weeks super early and I've been crazy sick every since. I am miserable. I work 3rd shift and do a lot of walking. I just wish it would pass. I miss food. Already.
