Please help me buy a new pc

Hey everyone, I am a little bit poor so any money you donate it would mean so much to me. My dream is to become a league of legends streamer but my pc is very old and I can barely play the game, but my parents don't understand me, they think playing pc games as a girl is weird and waste of time but I hope one day I can become a streamer like pokimane https://www.youtube.com/user/pokimane and do what I love. I know how this sounds but this is very important to me and one day I hope I will make a living out of it.

Right now its very hard to raise money for a new pc, my parents are not that rich and don't really care about it so they won't help me.

If I can save school money I can probably make 10$per month, I get almost no pocket money, which is not enough. please please help me, it would mean the world to me to have a new computer on which I can start playing my favourite game and streaming on twitch.
