How do I block out the guilt when I try to rest or do the things that I enjoy?

You just have to know that you are a human being with dignity and you deserve rest, not because of the work you do, but because you are human. Even God rested lolol you not the exception.
And just because you’ve been conditioned to believe otherwise, it’s ok and necessary just to rest and to relax and enjoy life.
Life and your dignity aren’t transactional, you don’t have to give something to “deserve” rest.
Changing your thoughts take time
Be patient with yourself
And trust the process
Even if others aren’t
