I would like someone in my life to be happy.

Between my 87 year old aging mom who thinks there is nothing wrong with her. Who thinks doctors are wrong about what she needs. Sadly her mind is sharp and she is just cranky and mean. My 4 mid 20 year old kids who struggle with jobs, relationships, the cost of life , and the world they live in. My husband who has a crazy stressful job. I am everyone’s sounding board. All day everyday all I get is negativity. I’m exhausted. I just wish one main person in my life was happy. Anyone else deal with this?
