I don't see the HUD on my screen, but in my inventory it says it is worn.

That means it's hiding off-screen.

Order the naughty thing back:

1. Detach the HUD into inventory.
2. Rightclick it in HUD, and select "Attach to HUD..." "Top Left"

That should bring it back.

If that didn't work, then you gotta do things the long way.

1. If you are wearing another HUD (from someone else), skip to #3 now.
2. Create and wear a temporary HUD:
   • create a cube on the ground.
   • right-click it and select "Edit" > "More" > "Attach to HUD" "Center". The cube will now jump onto your screen.
     You've now created an HUD!
     
3. Right-click this HUD on your screen. Select "Edit".
4. Use your mouse scroll button and scroll out (zoom out). You will see your LULU Command HUD somewhere off-screen.
5. Right-click your LULU HUD and select "Edit". Now you can move it back into position again.
