Maybe you're just burnt out from too much writing software. It might feel refreshing to get other hobbies that don't strain the thinking part of your brain so much, like jogging, baking, or gardening. Or if intellectual activities are okay, then learning an instrument and music theory might be another good one. After a while of immersing yourself into this, computer science may seem interesting and fun again. It may be that you don't rekindle your passion for a while.
