I have heard others talk about the negativity that can go along with having Asperger's. I may be very naive to this, but I haven't encountered it yet. The thing I get a lot of is, "You? Autistic? I don't believe that since you are a teacher and etc." It's like people expect autism to cause us to not be able to function in life.
I am not an expert in the field of autism. But I am autistic. So I think I have a right to speak words of advice. And you may very well be diagnosed with it too. For me, it was an incredible relief when after careful professional evaluation, the label was applied to me---"You have Asperger's, and perhaps could even be labeled High Functioning Autistic according to some clinicians." Now, I had resolution in myself. I knew, after many years, a better understanding of myself. That is the most important thing---your own well being. Don't worry about others and how they think of you. I believe that once you have a positive image of yourself, others will too. And I sense from you so far (even in just these brief few postings) that you are a nice person. Don't forget about the PDD-NOS autistic label too (not otherwise specified), you could even be considered that. No matter what you find out, you will still be you. But knowing what is going on, Asperger's, etc., should be an incredible relief.
Look forward to your appointment. I remember the nervous twinges when the guy was looking over everything and then began his diagnosis of me. Once he said "Asperger's" I felt a tremendous unusual rush of relief. After all those years, I finally know that I was not the only person in the world like me. I used to think I was a one of a kind freak. Then, I felt like I had just gotten my ninth tattoo (I have eight tattoos). That label will go with me forever, just like my tattoos. And I am proud of it. Now, in the wrongplanet, I can talk to many similar to me. And it is fun. I feel better about myself. Enjoy life, and good luck.
