A belated welcome to Wrong Planet. Very late diagnosis often stirs a lot of emotions. Why would it not? Having to redo or re-experience something you thought you were done with is very hard. You are finding out many things you assumed about yourself all these decades are not true. Tough to handle.
Since you have been operating under some false assumptions for so long, figuring things out is going to take some time. This can be frustrating, especially since an autistic trait is needing certainty. You need to let your autistic brain do what it needs to do. Sometimes, this will involve some setbacks. It's all part of the process.
Good luck
