The same thing happens in America too, unfortunately. Write or Wrong, I hope you have found some support for yourself like a frum therapist or a rebbitzen type to talk to. You have gone through this for many months, make sure you get some support for yourself so you can take care of your family.
Try not to spend too much time being upset with others that wronged your son. I know it is hard but it is a TOTAL WASTE of time. Focus on your family. Put that emotional energy in them. And of course continue to daven and do mitzvos in that zechus.
