This list and ASD describes a cluster of behaviours. It's unfortunate to not have the diagnosis and closure you were hoping for, but at the end of the day, a label is just a label.

What characteristics from the two lists (mine and ASD) impacts your life or the life of others most? Tackle one thing at a time. Talk with your therapist and let them know the specific behaviours you're wanting to work on. Hopefully they support you through it.
