How do I overcome writer's block!

I have written my whole life. Stories, journals, blogs, poetry..etc.. About 6 years ago there were a couple of major changes in my life…and I stopped writing. I felt as though I was too jumbled up to write… like it was all too depressing. And I haven’t been able to write anything of value since. I used to be very talented with words, what has happened to me?!?!?! How can I overcome this block?
