Negativity in 10yr old

[OAPM1]

I am really getting worried about my daughters behaviour.  She is never happy with anything that she does.  Although we have always tried to give her constant praise and love.  She thinks "everyone" else is better than her at everything, school, sports, circumstances whatever.  She can not accept not winning at sports or making mistakes in her piano playing or her school work.  she beats herself up verbally (and calls herself all sorts of names as far as her vocabulary can go).  She is also showing signs of wanting to punish herself by pinching herself, or slapping herself and has actually started saying things like "I feel I have to punish myself because I deserve it".  she calls herself dumb all the time.  I try to reassure her all the time that she is not and try not to overact, but I must admit sometimes it is so difficult to deal with the constant crying and ranting and raving for what seems to me like a trivial reason, that I do get upset with her for throwing the tantrums.  It has got to the stage where I am afraid she might become self harming in the future.  Am I overacting.  Is this normal pre puberty behaviour? I also have to say that she has always been very slow in doing things (but is of normal intelligence), and she has always been very reserved and usually very controlled outside the home.  She can also be very mean to her sister who she deems as been a lot cleverer than her.  I am so worried that I have consulted a psyhcologist from the school? Appreciate and feedback. Thank you!

Oh thank you so much...she is actually very good at sport but once she stopped winning  that became a problem.  She doesnt want to go anymore, I think she doesnt see that others are getting stronger as well she just blames herself for not being able "to do it anymore".  Luckily, she eats well right now and I cant see any abnormality in that behaviour, so far. But will certainly look out for any signs.  I am trying to find non competitive things that she can do and enjoy without putting pressure on her.  I signed her up for a painting class and although she went she complained after two sessions that it was boring. I am looking for something fun that I can do with her that is just for the two of us and both my husband and I are continously reassuring her, she doesnt seem to believe us, hopefully with time and the help of the therapist with whom she will be assigned to things will get better. I appreciate your feedback. Thank you so much.

These are signs that she is not happy with herself, is insecure, and feels inadequate.  You are right to be concerned.  She needs to feel good about herself, know that she is special, be happy with who she is.  She needs to find something that she is good at and can take pride in it.  Have talks with her about trying not to be so hard on herself, that nobody is perfect, that things change, that her feelings will change over time.  It is hard for girls growing up. They compare themselves to other girls, and envy the popular girls that are happy.  They do not know how they measure up.  Her behavior is typical behavior of a girl that would become anorexic, so watch out for any abnormal eating habits.  If this happens, it needs to be caught soon so it is corrected and doesn't go on for years causing damage to the body.  Keep a close eye on her and make sure that you stay connected with her.  The school psychologist is a good place to start, but you may want to get a counselor down the road if things do not change.
