7 weeks. Feeling sick non stop!

I am 7 weeks pregnant and I have felt nauseous for the last 2-3 weeks!! I haven't thrown up- but have that feeling all day and night long like I am going to. Nothing sounds good to eat...ever!!! I do eat and when I do- I can only eat a few bites before I feel sick to my stomach. On top of all this- I also have a cold and I am congested! I can barely stay out of bed when I am home and I feel horrible bc I have other kids to care for too!!! I can not give them the attention they need because I feel sick non stop!!!! This is the first pregnancy where I have experience such symptoms. 😒 and to be honest, sometimes I feel like I am not going to make it!!!!!!  Is there anything I can do to make myself not feel like this alllll dayyyy, everrryyyy day!! 😔😔
