3 y.o still struggling, hitting, biting, throwing, pinching, screaming, etc

I wrote almost exactly a month ago about a transition my 3 year old son and i were going thru- moving from our home into a friends, and now we have moved into our own place as of almost 2 weeks ago. The aggression is constant, though better when it is just he and I. Of course those around me attribute it to a lack of discipline but I see a boy who is hurting and who is very angry and frustrated. I am not sure how to help him and feel very frustrated with the other people in his life for only responding to the negative behavior and setting up this cycle of negative attention. I just wish I had a village, more support and more people to love and care for him. Just seeking some support and thoughts of how to help him through this.
