Pride

So i moved out my parents house two weeks after I turned 18 during my senior year and it’s been rocky but I recently left the place I’ve been staying at for over a year where I was living with some other family members so my aunt let me stay with her for only 2 weeks so I’m at my parents house and idk how to say I wanna come back home I’m scared they won’t let me then I really won’t know where to go. I’ve been going through a lot and I feel like I won’t have their support. How do I ask them can I come home because I know they are gonna ask why I wanna come back because I put up this guard like everything is ok......
