I just joined this group within minutes and I did so because I am having a very big problem with my 7-year-old.  

My younger daughter and I picked up my 7-year-old from an afterschool program.  We told her that we bought her a present.  Instead of being grateful she asked what it was and scolded me for not buying what she wanted.  She threw a fit the entire ride home.  I told her that she will be in timeout immediately and for some time once we got home.  I also felt that there was no way I was going through anymore of this without talking to professional.

When we got home, I put her in her bedroom and she yelled and had a trantrum the whole way.  When she got to her bedroom she was upset and soon kicked the door.  I went in to restrain her and warned her not to do that anymore.  After I left her be, I just cried and cried like I never have because of feeling like I have entirely lost control over her.  I know I have to bring her in to see a psychologist because it seems really emotionally strained.  My question now is, does anyone see what I did wrong or what I could have done differently?
