Writing after losing my spark

I really should start writing again. I don't mean just putting words down, but creating art. Answering questions, doing assignments, and messaging my friends doesn't count. I used to string the words in my head together into poems, and I painted my thoughts out into stories. Maybe its just an excuse, but it has become extremely difficult to get myself to do that again. Ever since the death of my best friend, the one who inspired me to write most of my poems. She was a great friend, one of the best people I ever met, and she didn't make it to 17. I've said things to her while beside here grave that are more profound than anything I have ever written down, but I just can't get myself to really write like I did before.
