Need Money.. Not Supportive Parents

I know some of you will be thinking “well get a job.” I’ve been thinking that too.. trust me.. but I can’t get a job because my parents just want me at home doing favors for them. I recently converted to being pentecostal, God changed my life for the better and God has been blessing my life when I go to church. I’ve always been on my own but going to church helped me make new friends that are great influences. The thing is all of the youth are going to a convention this summer in July and I need at least $300 to go😔 I don’t want to tell the youth about how my parents don’t give me anything because I get embarrassed.. so what can i do to raise money? I have a little bit of time but any ideas will be amazing. God bless you all
