Depressed…

On my phone, I occasionally see an anime picture, four girls and two boys (a middle-aged couple, an old woman, a teenage boy, and two sisters). Just that, and I feel depressed… In Japanese cartoons, the protagonist's sisters are drawn like AV (adult videos)… And I happen to have an older sister and a younger sister, which makes me even more depressed. Watching for a while, I lose my appetite; watching for a long time, my heart might fail! Am I having some psychological issue? Family members: older sister, younger sister, mom, grandma, maternal grandmother, and a father-in-law… That's all that's left. I don't know if it's an occupational hazard; if I die after retiring, it won't be worth it.
