When seeking a diagnosis is it essential to have input from someone who knew me in childhood?

Thanks to everyone who responded to my previous question. I got looks of helpful answers.

My next question is about having an assessment. 

I have read that assessments ask for information from someone who knew me when I was a child. My problem is that I can't think of anyone who I could ask to do this. There are reasons why I don't not think either of my parents would be suitable options.

Is it a necessary part of an assessment for diagnosis to have information from someone who knew me in childhood? Is it even worth bothering asking my GP about seeking diagnosis if I know that when they ask me about this I already know there is no one to ask?

  • Whether they want it will depend on their particular assessment protocol. I had the type which is largely based on observations. I felt unable to ask my family but asked my best friend (who has known me since I was late teens) to fill in the observation forms. I also asked my college tutor (who has also known me for nearly 20 years) to write a statement. I also provided quotes from my school reports. The assessors said they wouldn't normally be able to give a diagnosis without family involvement but made the exception because I had provided extra evidence and clearly explained my reasoning for not wanting my family involved.
