What a terrible dilemma. You are a decent person trying to do the decent thing but I think you are being used. You don’t really know this woman. You only know what she has chosen to share with you online. She is blackmailing you emotionally by her threats of death if you don’t take care of her. You really don’t know if the pictures are real or if the “friend” is telling the truth.
The fact is that a hospital is unlikely to keep someone in a bed if the person doesn’t need it. There are sick people who do need the bed. The hospital doesn’t want to incur more expense by keeping her there. I think this woman is taking advantage of your generosity and good nature.
As an American, she can turn to the American embassy for help. I suggest you give her this address: http://manila.usembassy.gov/service/information-for-travelers.html. They can do far more for her than you can. Then block her from your phone and your email. This is one gamble that you lost. It’s time to cut your losses and leave this “game”.
Meanwhile, please do work on getting your gambling addiction under control. It has now sneaked into other aspects of your life. You are vulnerable to more hurt if you don’t treat the root of the problem — an addiction to taking chances. Look into treatment programs in your area or find a therapist who specializes in addictions. You deserve to have support.
I wish you well.
