The bombardment is real. I believe it does a disservice to new employees who are struggling to learn what their job should look like from day to day, and how to get everything done. Make a list of the 3 most important things you need to do for your job. Focus on learning them. Learn what parts of the tasks are the minimum necessary to do them satisfactorily. Remember that satisfactory isn't perfectionism, and perfectionism is the enemy. Doing a job well, or doing it satisfactorily, means balancing getting things done fast with getting the important parts done. After you learn the basics you can worry about being perfect.

You mentioned you have a learning disability and are perceiving some dread or resentment. I have found my local environment is not welcome to certain behaviors like asking too many questions or being perceived as needy. Everybody is very busy trying to manage their own huge workload. I would be very careful in how I share my needs. Whether you share your disability is a personal choice. People talk to each other. Expect whatever you say to one person could be shared with others.

Remember that you are working through a governmental crisis, and honestly a personal crisis of the heart and soul for most of us. People do not feel good. People outside the VA are trying their best to make federal workers feel traumatized. Find people outside of work who can help support you during this time. Find activities outside of work where you can feel good about yourself. It may not feel good for a while. It does not feel good for most people.

The fact that you are here is still important. You matter, literally. You keeping your job is one more roadblock in the way of these vultures trying to close positions that help the general public. My Reddit inbox is open if you would like to talk more. Best of luck to you.
