How do you stop treating everything like a task and learn it's okay to rest?

How do you stop treating everything like a task and learn it's okay to rest? It feels like I have been treating everything in my life like a task to finish. For example, I feel like I have been treating a lot of my mental health struggles as tasks to finish. I get so obsessed with certain end points, and am really aware of my process of healing. Even when meditating, I get scared that I am not doing it right, and I feel like I just keep wondering how much time there is left on my timer. I can't even really honestly enjoy media without turning it into sort of a task. Like the whole time I will be thinking about how I need to finish it, and will replay the video if I feel like I didn't watch it right. What do I do?
