Confirmed autism for my 2 yr old

Today I was confirmed that my baby girl, my 2 yr old daughter is autistic.. it was like a bucket of ice cold water thrown at me.. I knew deep down that my daughter is autistic ( momma always knows) I feel like I failed her in some way and even tho I have a village of people to support us I feel like it’s just her and I alone in this.. I have read and kept myself informed for this day.. what’s my next step? Do I have to quit my job? How can I help her? Where can I get the help I need? Question that I have asked myself.. this doesn’t change the way I see her.. feel for her.. I love my baby girl.. nothing will ever change that.. I just want to be able to help her as much as I can..
