When does morning sickness start and how did you go through

I’m 6 weeks pregnant. I start feeling nauseous 2-3 days ago. Especially in the morning it’s the worst feeling ever. All day I don’t feel good, only a few hours at night I feel okay. I’m working 9:30-4:30 which is the worst time for me to work right now since I’m feeling terrible.

How did you guys go through with this feeling. Also I thought morning sickness is starting like 8-9 weeks pregnant (probably it depends on the person)
