Help me chase my online dream

Hi, my name is André, I'm 19 years old, and I've been around computers since I was a child. 2 years ago my mom got fired of her company, and my little brother ( 6 years old ) is going to school, and she is doing her best to give him education. I've tried to get plenty of part time jobs or real jobs, but my country is really a mess at the moment and I can only get small jobs who end up in 1 month.  So, to help the situation, I'm going to follow my dream and dedicate to online gaming, ( which is already a sport in asian countries ), and for that reason I need a new computer so I can stream while I play, this might be confusing to explain, I'm doing this as a last resource, my family needs help and this is the only way I can help at the moment, because it's what I'm really good at! I don't expect any big donations, even 1 cent helps! Thanks a lot.
