Woke up to my mom text and voicemails

I’m so over my mom disrespecting me. Sometimes she’s there for me , most of the time it’s this. So a month ago my boyfriend friend wanted to send him money on cash app and we don’t have a bank card so he sent it to my cousins cash app & my cousin said it went though and went to take off the money off his card for us and gave it to us. So 2 days later he text and say, the money never went through and screenshots proof so I’m like well you said it did & he said he thought... so he was like that wasn’t even my money on my card it was your brothers. So I explained that it wasn’t our fault and that my boyfriend wasnt working at the time for medical reasons and when he does start he will pay. 2 days ago they texted and I told them he just started back so wait 2 weeks and they seemed fine with that. So last night my mom called and texted and left voicemails.

BTW my brother is 17 ( smokes , drinks , fuck & does what he want ) she act like he’s 8 years old.

When I need someone to talk to , sometimes she gives advice , sometimes she says I’m grown and neee handle my shit by myself & half of the time I get this type of energy. What should I do?
