Where do I go for help when my elderly mom is recovering from pneumonia but lives alone?

 I live in a different city? As most of you know my mom's situation about being scammed a while back,I'm confronted with a situation where she sucame to  pneumonia and out of hospital but recovering slowly and I've been with her  for almost 2 weeks but need to get back to work in another city.She lives alone and has no resources at all since she was scammed but doesn't want to tell me who did this.She lives in texas and I work in Los Angeles.My boss can only be sympathetic for a while but I can't leave my mom to be alone.I've been doing all the cooking and cleaning for her.She's too weak to do this.please....I  need some help as to where to go in Texas.
