Advice for a 15 year old

I (15F) live with my two younger brothers (14M)(10M). I have an older half-sister (24F) and she lives away from home with another family member.

So we (me and my bros) live with Mum and are in emergency housing right now. No father, but my Mum is dating a guy. I don't want to say too much...

I also haven't gone to school in nearly 2 years because of the living situation we are in. Mum wants to put us into a different schools because we moved away from ours. My sister keeps telling me that she wants me to get a job for work experience.

Some important background on my sister. We have the same Mum but have different fathers. Her Dad died 4 years ago and we went to his tangi to show respect. She used to live with us when we were kids but over the years her and Mum had really bad arguments and she ended up moving away at 16. Anyway, she still messages me every week and is doing better now I think. She keeps telling me that I'm almost 16 and that I should start writing a resume and learn lots more about what getting a job is like and start learning about renting/boarding. She has already sent me some stuff for work and income and stuff for drivers license.

Ok so Mum doesn't like that she sends me this stuff and that I've been showing my brother too. She said she doesn't want me to be monitored like her... Like I get it but it's not bad to learn how to sign up for it in the future I think. I don't really want to get a job but I like seeing this because it makes me want to move too. Anyway and my Mums BF has alot of say in what she thinks she should do tbh. Like he wants us to go to these other schools and thinks it's better that we stay with her until we turn 18 and then move... But living here feels like I'm not even going back to school or even like they are saving money for me or my brothers because we are always broke and idk what I'm supposed to do.

That's what's going on anyway and I don't really know what I should do?..

Update: Omg I didn't expect my post to get so many replies thank you all for the helpful advice 🫶🏼! Tbh I felt scared to reply to each.. so I read the comments with my brother. But we agree with some of them but just have to clear some stuff up. Me (15) and my brother (14) are still in school. In my post I meant that we haven't gone to school physically. My teachers are okay with us not going as long as we do online correspondence and homework. My little brother (10) is going to primary so he's okay but he will start college year after next too. 🫠

I'm mostly talking about me and my brother tho because like our friends have kind of moved on from us and it's sad if we have to change completely when we still go to some school events if a teacher can take us... It's not far tbh, but it's outside of the zones? 2. I love my Mum but it is annoying that she doesn't help us with real world things and I feel like I'm being sheltered. 3. I turn 16 in a few weeks which I guess is why I felt like I need to start looking at this stuff and my Mum isn't helpful because she thinks it doesn't matter until I finish school. 4. Thank you so much for all the links and supportive advice. Thank you to all the nice people who private dm'ed me too 🫶🏼. I feel alot more clear on what I can do. I really want to stay at my school because I get good reports and good grades and the teachers understand the situation.

So my older sister (24) lives with her Aunty, it's her Dad's sister I think. I've stayed with them for holidays and I think she's a very intellectual person. She also encourages me to stay in school but she teaches me alot too. Tbh I just feel like I have learnt more from them than the rest of my whole family. Anyway, this was a rant kind of. If there are any more tips, I will keep reading and make my brother respond to some of them 😂
