Death of the cyclamen

My mom and Joan got me a beautiful cyclamen when they were here visiting. It was a lovely gift, but little did they know, I have the green thumb of death. And true to form, the thing is slowly dying... and I've only had it for a week and a half! I'm pulling out all the dead flowers but the leaves are yellow. There are still new blooms coming up, but they are white rather than pink. I'm watering it well from the bottom... maybe it needs a bit more sunlight. Not sure. Guess I'll start moving it from the table to in front of the window during the day. Maybe that will help it.
