Helpline or courses for parents to adults who are struggling

Well, I finally had a carer's assessment and got signposted to the NAS for information and possibly a course for parents to adult autistic people (or for ND families as a whole).  Is there such a thing?  Or have I been fobbed off?  

Is there even an NAS helpline any more?  (And apologies if I've missed it due to feeling very stressed about things).
