Been super stressed and only in first trimester

This is my first pregnancy and I have to say I've had a lot of stuff going on I can't really handle my emotions and I had work issues and problems with my sister we got into a altercation last night I just don't want to stress while I'm pregnant and I know it will happen I just don't want it to be so often how are y'all staying calm and handling yalls emotions bc I'm legit happy one minute and angry the next and everyone says they can't stand my attitude and I don't need to act a certain way for the baby
