How anyone has constructively overcome their difficulties, due to autism or otherwise.

All these wonderful ideas which I have not done make me feel a failure who has missed opportunities. Too late now to sort out so suicidal will be my take

Open a new post for this, as has been said by PA.  You will then not move this into directions which it wasn't intended.  Thankyou.

Also consider again getting specialist professional help.  Seek help from your probation officer or psychiatrist  Perhaps a local autism charity if there is one near where  you live, or Mencap. If you can afford it, get help from a private psychiatrist.  Perhaps print out what you have written here and the answers you have received and show them. Contact the help line and ask if they can give you some numbers of specialists who may be able to help you, not forgetting talking to Samaritans as much as you can.  And try some very deep self analysis. Many of your problems which we have read about in a multitude of threads are way, way, out of our depth.
