Stressed for Long Time

I'm still experiencing symptoms of stress.  This morning I was making my son breakfast and he was getting bossy.  I scolded him for it and he apologized.  I had a small weeping spell after that.  I think crying is how I release stress.  I don't usually like to talk to my husband about when my son acts up because I don't want to add stress to his life.  Sometimes it's hard for me to ask for help because I don't want to bother anyone.   What I ended up doing is storing up all this stress and making myself sick.   Today, I've had diarrhea and heartburn.  I drank some milk to get rid of the heartburn and threw up seconds later.  I've never been a relaxed person.  It is something I need to learn.  I'm going to lay down because I feel tired.
