Any trick to get a new phone?

I have been using a phone since past 6 years which is 3/64GB, it lags a lot nothing works in it and O don't even use any social media apps like insta, fb, etc...

I don't chat with people don't talk on calls I just do some heavy work on it to be able to fulfill my basic needs like bodywash, toothpaste, moisturizer, undergarments through some high cashback offers which needs lots of efforts and patience, but despite all the efforts I'm unable to save money as nobody gives me any money.

I wear my teenage clothes that somehow fits me because I've lost weight , i don't do any job and I'm stuck at home I can't get out of here until I learn something through a phone to get a job, I'm the third and the neglected child that has been living like this since always, I can't even recharge my sim to keep it going.

There's no way to change this situation so don't recommend me asking for money from my family members it's not gonna work infact my own sister who lives her dream life "luxurious life" already owes me a few thousand rupees that she borrowed from me when i was in school (the money was my savings that was given by several guests/relatives as a kid), even though she clearly knows that I've been yearning, I'm literally in so much need she never returned my money (she hates me because she's insecure of me), she always made fun of me infront of all of our guests and everyone, well that's another story but for now PLEASE LET ME KNOW A WAY TO GET A PHONE MY PHONE COULD STOP WORKING ANYTIME AND I'LL BE LEFT NOWHERE TO GO

PLEASE HELP ME!!!
