AIO If I go to the police about these texts from my (F37) mom

For context, im 16, my dad and my mom are divorced, and he has full custody of me since my mom isnt in the right mindset for children and is abusive. she doesnt like my dad at all. last night she said me a bunch of these wild texts.. it started because i wouldnt pick up her calls because it was 12 and i wasnt awake, i hadnt texted her in a couple days. the blanked out stuff is my name. I talked to my dad about it and I brought up going to the police station and he said he wasnt sure. She also sent him a voicemail saying he should die and cussing him out. Shes sent hundreds of welfare checks to my house unsolicited and unneeded so I'm not really sure what to di
