New member with no-where to turn

I am a mum of 3.  2 boys 22 and 20 (eldest is diagnosed with Asppergers), 12 years old daughter not diagnosed but suspected.  We have got through the early years with my eldest 2 but now my Dd has started secondary school and she has fallen apart.  She cries daily and even phones me from school.  I am going back to the doctors for help but can’t see a solution anytime soon and she is falling apart.  Feeling quite desperate at the moment with no easy fix.
