I feel like the absolute worst

Im 8 weeks pregnant. I can’t seem to enjoy chewing on sour stuff like recommend by my friends who are moms to not feel sick. I’ve been nauseous & giddy minutes when I wake up & mins before I go to bed. i don’t feel good in my own body and skin. I don’t understand what it wants or what’s triggering. I can really feel sick the whole day. I would cry because I didn’t think it would be..this tough. help..I feel like giving up
