how do I quit AIT?

I’m currently at AIT for 12W at Gulfport, MS and i’ve hated the experience I’ve been feeling depressed since I got here and I want out currently i’ve been on holding for a few weeks and we have no idea when we will be able to get classed I just want to go home. I’ve heard all the stories of it’ll be faster to just get through it but I can’t see myself in the army any advice?
