Showing good character

Q: I have my friend from France and he asked me this question:

His father was a Catholic before, and now he's a Muslim. When his father was a Catholic, he was a good leader to them but when he became a Muslim, he is always angry at them even though they don't do bad things. My friend said that he always crys because before they were happy and full of love but now his father is always mad at their mom. Their mom is always getting hurt by him. My friend wants to know if this has anything to do with Islam?

Solution for an unmarried person who has high sexual desires

Q: I have a very embarrassing question but I can't handle it anymore. The thing is that I am in my twenties, I don't masturbate or speak to any guys but I toss and turn at night. Unable to sleep because of my insane sexual desires that are now eating me alive. I will never masturbate but I can't handle this. It's too frustrating. I want to scream in pain and I just know that the advice everybody will give is try to get married but it's not in my control at all. If Allah Ta'ala isn't willing for me to be married right now, if He hasn't sent anybody my way for me to be married to then how can I?
