Autism, Syncope and medical help for the effects of Autism

Hi all 

I have recently been diagnosed with Autism (25-year-old male), and alongside this, I have suffered from Syncope ( the medical term for fainting). 

I have talked to my GP about my fainting, and they say there is no cure. I have found it difficult to prevent my fainting in the past and am unsure how to resolve it.

I am also isolated, suffer from anxiety, have social difficulties and am depressed and stressed. I suffer from suicidal thoughts because I want to be happy and progress, but I feel stuck. 

I am planning on contacting my GP to go through my recent diagnosis assessment to figure out what solutions there are to these issues. 

I have tried talking therapy and Cognitive Behavioural Therapy (CBT) in the past, but due to my restrictive interests and behavioural patterns, I find it difficult to change. 

Does anyone have any advice on potential solutions to help me through my issues, which don't resolve around drug taking because I feel that my brain is immune to stimulant drugs? 

I take daily walks to clear my mind, but I have been doing it for so long that they aren't impacting me anymore. 

I am also job hunting because my last place of employment required a 3-hour commute, both 2 and from, so 6 hours commuting a day by bus for an urban planning role.

Finding a job to accommodate my mind is quite difficult. I like being useful, but I feel that I don't really belong in most places.

I don't know how to cope and fix myself. I don't know how to socialise; I don't have friends. I have always felt different. 

Cheers for reading. I imagine these issues are quite common amongst those neuro-diverse. 

Does anyone have any coping mechanisms or tips?
