I am amazed that you have taken care of your FIL for three years!! What strength you have combating all the issues. I am no professional by any means. From what I read I feel that it is maybe time that you step back and let someone else do the care. Especially if his own family gives you no support at all. Do you have a care team set up that meets to discuss issues? It's not that you can't do the work -- you've shown you can for the past 3 years --but is it worth risking your health and well-being because you are not supported at all? There are many wonderful suggestions in above posts that I would seriously take into consideration. I spent close to 5 years trying to convince my brother and sister that my mom was having dementia problems. They just wouldn't listen. Hardly ever visited - only for short times. They did help out during her last years but they missed so much of her life prior to that. She has been gone for 1 1/2 years now but I still have resentment towards them for not even wanting to meet to discuss issues with them. Plus all the work that my husband did as well. No thank you's. Nothing. If there is no "family" support system work with other professionals to set something up so that you can have time for yourself and your family.
