Am i too young?

I'm 17, and I already searching for a job, which isn't quite common in my country cause you'll have to be at least 19 to get a real legal job, and I'm searching to help my family economy and my struggle, i had to buy some medicine for myself and just in case something happens, i have my own job to stay alive, but sometimes it feels like I'm very young for this, I'm not even legal to work yet, but i desperately searching for a job, i just hope everything will get better eventually, and i can just rest ;)
