Morning sickness

Is there any morning sickness tips! I'm struggling really bad ATM I'm 7 weeks and it's actually breaking me. I haven't actually been sick yet although I've been close so many times. I know no one likes to be sick but I end up in tears when I am! I was sat at work this morning holding back my tears and trying not to be sick and my colleague added I looked like shit... I just wish there was something to ease it! Thanks
