Think back to your childhood when you were most artistic. What did you really enjoy doing? What was the first thing you reached for on a rainy day when you felt like "making something"? - Clay? Coloured Pencils? Paints? Felt Tipped Pens? Start there. Just try to reconnect with your creativity, with something really familiar.
Then as you start to warm your creativity up again, the choices might seem clearer to you. Perhaps you find you really love drawing (for example) and you want to explore that a bit more. Or perhaps you start itching to try something completely new. Then you can set aside a few weeks to maybe take a class in a new subject, or get some books out the library and just play around with an art form that's new to you.
Have fun! That's the most important part
