We desperately need help for our son

Hello,

we desperately need help for our son. here is his
profile:

8 years old male, slender, has allergies to milk proteins, egg whites, soy and some of environmental allergies, afraid of darkness (sleeps with night
light), likes to sleep with his baby blanket and stuffed animals and is sensitive to sounds. Says has nightmares (though do not usually wakes up from them), has leg pains, usually at night (very severe at
times). He is afraid of heights and bees, used to be afraid of any animals (though is getting better now). As an infant had stomach reflex, allergies, eczema, had a skull defect, where the right back side of it was bulging out. As a toddler, he used to wake up from
a nap with his head being very sweaty. Does not take changes easily. When he was little he would not sleep anywhere, but his own bed, he was 3 years old when mom colored her hair a darker color – he cried and hid
behind a char. LOVES sweets and white bread, does not like to eat fruits or vegetables. He is smart, has very good memory, contagious laughter and a great sense of humor. Prefers indoors to outdoors. Does not like to be kissed especially by people outside of
immediate family. Mom can not kiss him with her lipstick on. He is sensitive and notices changes in
other people behavior. He masturbates a lot, especially when upset. He could never compromise. Gets easily upset, does not seams to learn from his mistakes. If punished for a certain behavior, even though will cry immediately and become very argumentative will do the same thing may be even the same day. Does not take “no” for an answer. When upset will cry, yell; throw himself on
the floor and kick his feet and this kind of behavior happens several times a day for different reasons.
Even when things seem to be going OK, all of a sudden, he would come up with a subject that would throw off
the balance. LOVES to watch TV, very good LEGO builder (used to
play with it all the time, but now TV is #1). He would start doing a task and wonders off to do something
else, completely forgetting what he was supposed to be doing. Ever since he was little, can not tolerate any
competitive games. He is afraid to lose. He dose not like to do his homework or do any kind of
practice. He has been taking karate lessons since he was 4, but still has a white belt (beginner), do to luck of concentration and unwillingness to practice at home. We had many incidents when he did not wanted to
do his homework and would argue and yell and cry for hours and in the end would do it in 20 minutes. He wanted to take painting lesions, loves them a lot, but if the teacher asks him to practice anything at home- refuses to do it. When drawing, he prefers to
draw sharks, spiders and pictures with blood and scary faces. He likes to be a center of attention by being silly. Gets his feelings easily hurt, and reacts to
every word. Comes home and says that everybody laughs at him, or that he has no friends, but yet may play
with a few kids that day. If he likes a person, he does not like to share him with other kids. He is not a very good sharer. (Last time he asked for a spatial kind of food, when I made it for him and his 2 year old sister, he cried and yelled - why does she always
have to get what ever he is getting?)

Thank you, very much!
