I can’t make a diagnosis on the basis of only a letter, of course. But many of the behaviors on your list are consistent with what people with high functioning Austism or Asperger’s report. You do need to see a mental health professional to get a more certain answer.
If you were seeing me, I’d want to know what it means to you if you do have such a diagnosis. For some people, it is an enormous relief to understand that there is a reason for what they do and feel. Other people find it very difficult to accept their difference. And, of course, there’s everything in-between.
What I most want you to know is that we all are given strengths and challenges. It’s not what we’re given that matters so much as what we decide to do with it. Many people with Aspergers will tell you that there are talents and strengths that come with the condition that they wouldn’t trade in for more normalcy. They’ve found ways to make it work for them. Einstein, Mozart and Tessler are said to have been on the autism spectrum, for example.
You might be interested in books by Temple Grandin, a very gifted woman who is on the autism spectrum and who has been explaining it to the rest of us for many years now. In 2010, there was even a TV movie made about her life.
I hope you will seek out an evaluation to get the answer to your question if it will give you peace of mind. But more important, I hope you will love yourself as you are.
I wish you well.
