I’m about lose it...

My 2 year old, who recently just turned 2 is so unruly it’s almost unreal! She fights me and her father on just about everything! Getting dressed, brushing teeth, changing her diaper, eating, getting into the car seat etc...she hits, scratches, dig her nails into you, and throws things. She screams and I mean SCREAMS this high pitched scream, she also cries all the time. Another thing she sometimes wakes up in the night...

When she was a baby she had very bad colic that was a horrific nightmare, but that eventually got better and now she almost started back up again with this crap.

We are at our wits end she isn’t horribly behaved “all” the time, she can be very sweet and loving, but we are very concerned and mentally we are barely hanging on. My son had his moments but he wasn’t like this, I am wondering is this normal? Any suggestions on anything on how manage her behavior l? I don’t know sometimes how to help her, we love her very much and just want the best for all our kids.
