Hello and thanks for using JustAnswer.com:
The short answer to your question is "yes." Autism
exists on a continuum and it is certainly possible to have autistic traits without meeting the criteria for full-blown autism.
You have had your daughter evaluated by a psychiatrist, who has ruled out Asperger's Syndrome, but she indeed does display many of the traits. Patients with Asperger's Syndrome often have good verbal ability, but due to their poor reading of social cues will not participate in conversations because they find they are rejected by peers. Thus they have high levels of anxiety and depression and often are given anti-depressants.
You may find comfort in reading some books by Temple Grandin, PhD. She is a college professor who was diagnosed autistic at the age of two and has gone on to have a distinguished career. She has written at least six books on autism. You will enjoy them.
Your daughter is getting the help she needs, and as long as attention is given to her particular traits, such as the poor social skills, literal thinking, lack of tolerance to change, she should be able to finish her studies and will probably excell at a career in which she has an interest.
