I think you just have to make yourself. Write the most horrible conflict you can think of. The most devastating, horriffic tragedy even - no one's going to see it so be brutal and don't even worry if it is coherent - and then hide that away somewhere and writing normal everyday conflict will seem a breeze!
Then whenever you feel like you just can't write a conflict- you can look back at that exercise -or do it again and gain some perspective.

Also maybe keep in mind that if you create a conflict for your characters - you get to solve it too <3
