How can i get properly discharged from the army national guard?

Hey everybody, i'm 17 years old and a PV2 in the army national guard (michigan). I've been really gung-ho about being a soldier and been anxious to do this, however, some very tough times have fallen on my family in the past few months. i Ship to BCT in june, and need to know how i could get discharged to help my family. Long story short, my brother has cancer, my fathers gotten sick, and my sister is pregnant, and i'm the only one who has a job with security. I'm trying to help keep my family healthy and it's not a good time at all for me to leave. i would like to re-enlist later on in life but right now is not a good time for me to be gone for 6 months. please do not slam me because i need out, because i'll just delete your answer and tell you you're a jack. i'm 17 and trying to help keep my family and girlfriend all happy and healthy and seeing as i'm the only one who has the ability to work right now means i need to do this. so please, legitimate answers only and thank you to anyone who helps me. God bless!
