Is everything influenced by autism?

I'm six days from receiving my diagnosis and I've been trying to pick my life apart wondering what is autistic and not autistic.

But now I'm wondering if that is really a valid or the right question. For instance I told my assessor that I feel I play a role in

work and with family and  am only myself at home when I can recharge and rest (I live alone).

She said straight away that that is masking. I'm 51 so I'm sure I've been doing a lot of things for years and years that I didn't know I was doing.

Trying to fit in and knowing that I don't so pretending and just being exhausted by it all. 

I found the assessment itself quite triggering. Bringing up a lot of childhood experiences that I've blocked out but were indications of autism.

The diagnosis is new and I haven't told anyone, so I'm trying to get a picture of things and it's too confusing.

Like when I make a grocery list I make it in the order of the stores I'm going to and then by the layout of the store inside. I like the order of this,

makes me feel calm especially if the shops are busy.

Lots of things I do have me asking myself Is that autistic?  Or is there no separation?

Completely baffled right now.
