Please help me

So I have been going back and forth on myself about having autism. Everyone has told me “everyone is a little autistic” or “you do a-w but you don’t do x, y or z so you don’t have it”. Well Friday my boss got upset with me because I told her on the walkie talkie that “I’ll get back with you I’m a little busy” because I was helping a cashier wrap and I’m sometimes a front end manager to fill in. She thought I was giving her attitude but I over explained that I would never give her attitude. Should I tell her I might be autistic or should I just leave it alone? I stopped trying to get a diagnoses because I don’t tick all the boxes.
