For a few years now, I've thought on and off about the possibility I might have Asperger's Syndrome. The major symptom I have is obsessive interests, I've had these since I was a child. For example as a child I liked birds and sometimes that is all I would talk about, I would even make school projects about birds when they weren't suppose to be. I also have meltdowns (severe as a kid to the point I disturbed the classroom) and some sensory issues.

But I have the ability to read facial expressions and have some social skills (though as a child, they listed on my psych reports I didn't have any). also I look people in the eye when I talk to them.

A couple of my past therapists thought I had it, but other people say I'm too high functioning. I also have some sort of mental illness, they currently say it's bipolar disorder now, which complicates things.

Anyway, my main question is is how diagnostic is the interests? Does this show up in other disorders? Or is it a big red flag?
