I'm semi-diagnosed, too. My therapist says I have Asperger's Syndrome and High Sensitivity. My psychiatrist is against diagnoses of neurological conditions of this kind, as they are not mental disorders to be cured. I was also misdiagnosed by some other psychiatrist earlier, so I don't really trust official diagnoses, too. Getting out of psychiatric misdiagnose was really hard but now I am functioning again, so I am sure they were wrong.
You said you talk to a counsellor. What is their opinion?
Official diagnosis may help or not. If you need it just for self-understanding, semi-diagnosis may be sufficient. If you hope for some additional services, it would be obviously required.
