Angry and frustrated

I'm 39weeks tomorrow and the last two days I've been super frustrated and angry towards my family, boy friend and mother. To be honest I truly don't have a reason but every little thing they do or say sends me off the rocker. I'm starting to feel bad because I don't want to push them away knowing I do need the support of them but I can't help myself I'm just that aggravated😠 is this normal at this point of pregnancy? Maybe it's because I have nothing to do anymore? Or maybe because I'm ready to have the baby and nothing is happening. Are any of you mom's having this problem? Help please!😈😣
