Help! So tired, so sick... but I have to work!

The struggle is real... I am so extremely tired its unreal. I did not feel anything like this my first pregnancy. Each day it seems to get worse. I don't want to even get off the couch. My house is becoming a pit. I feel like I have abdonded my son. I get extremely nauseous and dry heave if I don't get something substantial to eat every 2 hours. Vomit maybe only once a day or every other day. I am not hungry but have to force myself to eat. I am having to work full time and had to leave today because I got so sick. I am extremely stressed because I dont know how to feel better and scared I won't be able to keep up working like this. Any suggestions? Thoughts? Anyone relate? Diglecis help anyone? Baby #2 you are worth this all but man oh man!!! 😥🤢🤮😴
