Fatigue and irritable

I am 5 to 6 weeks pregnant and feeling super irritable at everyone at home including my husband, FIL who stays with us, new helper, and my children when they dont listen. I am annoyed by their actions and bad habits I see everyday and having to mother everyone and nag even when they are already adults. I want to get away but I feel it will only be temporary. I try to be positive and forgiving but I cannot. Talked to them but still everyday there will be some form of annoyance they create to annoy. I feel super tired too working office hours and travelling to and fro at peak hours. My body muscles are sleeping and not ready for this pregnancy. I feel so depressed and tired. I want to feel happy about my pregnancy but my surroundings are too annoying 24/7. I am not exaggerating. Any ideas how to destress, calm down and be a loving person again and stop hating everything and everyone? I want to have a healthy mind and pregnancy but find it hard. I also worry if i will have any pregnancy complications due to my age 36 and my existing health conditions. I already have abit of subchorionic hematoma seem on ultrasound few days ago. It stresses me out to wait another month before the next appt.
