It's too bad that you have to force feed her. Have you had her checked for parasites? Is she wild caught? If you fed her beef heart you would have to put vitamins in it. If you can get one where you live, there is a tool called a pinkie pump that can liquify whole mice to force feed the snake through a catheter. This would probably be healthier. Good luck, I had a wild caught female and she died of an infection, even though she was eating.
