Can you use your hands okay? I recommend trying origami, sewing of any kind - cross stitch, knitting, quilting, and colouring in colouring books. You can do any of these things while listening to music, books on tapes, foreign language lessons, or while watching movies, or television. Sometimes it helps fight boredom and negative thoughts to keep hands busy too. (For me anyway)
I really hope you will be feeling better soon.
