Is this normal for late pregnancy ?

The past week I've been feeling really sick and not myself .. I feel really sick to my stomach, a headache, and just over all feeling really crummy .. Also my personality seems to have changed .. I am all of a sudden feeling really anxious and stressed out and nothing seems right .. This is my second pregnancy .. Also my son was at his grandparents for the night and as soon as I left and got in the car I had a complete meltdown which I have never done before .. I didnt know how to deal with out him home I literally cried until the next day when I picked him up .. Also even though I dont feel good Ive had a ball of energy inside even if I dont feel up to doing anything I still feel like I have alot of energy inside .. Ive also been starting to get extremely uncomfortable and not only in my stomach but in my crotch as well like very frequently .. Any suggestions ??
