Help me! I need a good camera to win my life and i’m a photographer very good

I am a 19 year old boy, I like the photo very much, I do not have money to take a better one so I can go on, I already have one, but it's very weak, from the photo I win my money to eat and dressed, I'm renting, I have a very low salary and the money I do not get at all, especially as I'm renting behind and it's going to kick me off. If you can and would like, please help me
