She is becoming increasingly paranoid and hostile. She runs into small issues (today her web browser window was smaller than normal) and gets very angry, blames members of the family, curses at us, yells, and calls us names. She generally seems mean and spiteful, and many of her comments are very hurtful. Her memory is showing signs of fading, she is slowly working on a hoarding addiction, and has less and less time for her family. Her addictions (online shopping, hoarding, wine, candy crush) are taking up legitimately more than half of her day and getting in the way of her relationships. She is convinced that her children are constantly out to get her and expects complete subordination while she calls us "pieces of sh*t" and yells because of something trivial. Lastly, she has begun seriously overfeeding our cat, 3 or more times a day. When we bring this up, or anything for that matter, she gets angry, tells us were spiraling out of control and projecting, calls us d*cks or something, and goes on doing what she was doing. My father works a lot and just can't- or wont- see this. Recently i have been thinking she needs help, and its only gonna get worse, but im not sure what steps are appropriate to take. She refuses to hear it from us, but she needs help.
