Emotional dysregulation- advice desperately needed

I struggle terribly with emotional dysregulation- caused by specific issues. I suffer mentally and physically. I have no support network and cannot access timely support. GPs in my region know little about Asperger's and do not recognise adult ADHD. When I need to speak to someone knowledgeable to prevent my anxiety escalating there is no one. I am only given the number of the Samaritans etc. Sometimes I cannot get through on the helpline or it is closed during certain hours. Any ideas what I can do? I have a worry I have been brooding over all day and its getting worse.
