Controlling one's anger

Q: I am getting angry and cannot control it. I do not stop to reason and calm down but I just blurt out whatever I want to say without thinking to my husband, and when he leaves the house I get back to my senses and think what is wrong with me. I have very bad scary dreams and I am very restless at night when sleeping. Secondly I want to know if rukya is permissible and can it be done by a female? My third question. I am in a 2nd marriage and I have kids from my first marriage. How do I divide my property, car, pension fund and money in the bank? I have one son and 2 daughters.
