Where do i start?

hello.  I have been through a lot of tests over the years, i am 44.  I have struggled all my life with various problems, depression. friends, partners jobs etc.  I sought help eventually and have recently been told my problems are to do with Excecutive funtions, which is due to frontal lobe damage as a child.  This effects hmm. ok just got a 'mind block'. can;t think of the words.  Anyway it effects lots of things i say and do. I am still a bit confused as a lot of my synptoms are what the symptoms are for autism. I was told by my neurophsycholojst that i was above average in my tests, and my results were all the way up the scale, from the 'dummies up to geniuses!  He has never had results like it!  So i have asked to be tested for austism.  any advise?
