I am so sorry you are going through this, wow I feel like I am reding my own story!! I have had bite marks and been in pools of sweat from holding down my difficult child 2 and it just kills you having to do that. My difficult child 1 has just started seeing a psychiatric and I didnt think I would bother either coz he just spits at them and wont talk to them but what I found was a psychiatric whois also a child play therapist, so they play with any of the thousands of toys she has in her room, all sorts of gross things that boys like plus a sand pit and many other things, and she can tell so much from the way they play , the dialogue that goes on and also they talka lot more and they don;t even realise it. He actually respects her and he has no respect for anyone, as her only rules are, respect her and respect her toys, apart from that they can do anything. And suprisingly enough they do! My difficult child 1 also spend so much time without his things too that it doesnt make a difference, man I know exactly how you feel. Unfortunatly apart from Play Therapy, I am only new here myself and theres not much else I can suggest apart from taking one hour at a time and know that we are all here for you!!
Hugs,
