hello nina..........you are in the hardest position for a mom and wife to be in.....you need to try to keep the peace and soothe your husband while fighting your own demons........this is certainly not fair to you....as hard as it is you have to speak softly to J......remind him that hitting or biting are not appropriate but also let him know that you understand that he is at his wits end........when he needs to cry.....hold him...........and gently remind him that you are in this battle together and you need his strength right now.......i am praying that God gives you all the help you need to get through this.i love you
