Sorry you are in such a tough position. If you belong to a Church, perhaps you can get some assistance there until the support comes through. Or possibly the Salvation Army.
Also, if you aren't, start keeping documentation on all of this, especially the non-visiting by your H. If he is yelling for increased visitation but not even taking your S to lunch when he stops right around the corner then the Judge will see right through that charade as just an attempt to reduce his CS requirement.
It's tough, but you will get through this and things do eventually get better.
