Are the voices influencing her decision?

My mother is schitzophrenic, same with her mother, which means they hear & or see spirits... my grandmother greatly influences my mothers decisions. for the last 7 years she's defied her court order & refused me child support. th3eres no reason not too, she's getting disability cuz she's crazy, & so is her husband, they're also ( don't think this is suppopsed to happen) both getting wellfare cheqs, together the governement gives em about 16-17 thousand a year, my dad made 4000 fishin last year, & 2800 this year(he was supposed to get 5600 but he was ripped) & damadged his knee fishin, so he's out now, & they won't give him workers comp cuz their rates will go up... so when my mom makes so much more, & also lives off her mom, & i'm her son...

Do you think the spirits talking to my mom, my stepdad, & my grand mother when they don't take their meds influence their decisions on this? I know for a fact that my grandmother doesn't take hers, & my mom & stepdad somtimes forget or don't bother cuz they're too tired to get up, or when they visit us sometimes they forget them... oh, & my aunt is bipolar, which my mother also has, (their whole family is crazy, that's why i'm with my dad) judge said it's the girls in their family though, & i'm guy, so i'm safe

So do you think the spirits speaking to them influence their decisions?( if yopu don't believe in the supernatural, then It would be the voices that they hear)
