Child Affected By Arrest - From Anonymous

My OH (other half) was arrested in front of our son last month. The impact this has had on him has been devastating. He has been wetting his pants at school and he has been lying to his teacher that he is ill and wants to go home. He is wetting the bed and has started to draw all over the wallpaper in his bedroom. I have asked for help but have been told that I have to pay for counselling for him and I can't afford it. No one wants to know and I don't know what to do. From Anonymous.
