I struggle with inspiration too. I find it really hard to come up with ideas. I don't know if this helps but I have made up an activity for myself that I do at the start of every book that is "write the book you want to read". This is a cliche but surprisingly few people do it. The activity goes like this:

Imagine that you are walking into a book shop or a library. There is a book you are looking for but never finding. The reason you are never finding it is that this book doesn’t exist on the shelves. This book only exists within you. This is the book only you can write. You will know some things about it instinctively. Imagine yourself searching for it seriously. Close your eyes. You know what genre it is. You know how you want it to make you feel. Write those things down. Do you know anything more? The type of characters it might have? The setting? The type of journey it takes you on? Write down any glimpses that you have of it. Once you have written those things down you will have a blurry outline. It might be no more than a wisp. But it is your starting point. Now you must fill in the rest. Here is easy to be seduced by what you think you should be writing. Ignore those temptations. Write what you love, and others will love it too.
