Exploring Mental Health Diagnosis Options

I’m looking for some other opinions on what people think! My whole life I’ve been a lot different than my peers. I’ve been going to therapy and seeing psychiatrists, psychologists and my neurologists for a few years now. I do have a good amount of trauma and ptsd so they could be over lapping symptoms I’m not sure as I’m not super educated yet. My therapist suspects BPD. Now I have researched and took the embrace autism tests for people more high functioning. I feel as though I may be on the spectrum. How do I bring this up and who do I talk to. Or am I crazy?
