This will be a random string of ideas.....but first, give yourself a break.

Go do something different... like macaroni art or basket-weaving. Maybe read a sci-fi novel and make a soundtrack in your head while you read. Inspiration comes in 2 modes for me: absorb and expel. Consider yourself in an absorb mode right now. Listen to other peoples music, maybe in a genre different from your own (this works for me sometimes). When I am totally locked up (see AD's anxiety descriptor above), I make a sound set of 10-20 presets on my favorite (or even my less used) VST or hardware synth. Go through some tutorials on
youtube for some of your gear you don't spend that much time in and deep dive into it's features. Pick up a new instrument or learn some new chords.
Always allow yourself to take a break from your art. You aren't driving an ambulance or performing open heart surgery. You're making music and you first and foremost should personally enjoy it. In no time you'll be 'expelling' so much you won't have enough room on your hard drive to hold all of the ideas.
My 2 cents.
