I’m stressed out

Next Friday I’ll be 3 months pregnant and I haven’t told anyone besides my husband because is through ivf (we tried for 8years on our own but we couldn’t) I’m stressed all the time and I know is not good for the baby. Two siblings live in our home with us and they stress me because they don’t want to clean and one of them eat my food because he doesn’t want to go to the market. Those things stress me. So i decided not to do Christmas dinner and new year’s eve dinner because no one offers to help me so I decided to go with my husband to have a dinner tomorrow night and no reunion. But now I’m feeling guilty because I’m the one who always reunite all members of my family at home. But no one had said anything about it. Sorry i just wanted to get this out my chest.
