Resume - need help😭

Ok, I'm 21 and ive only had 1 paying job my whole life. i was only there for 5 months and had to leave short notice because my sister kicked me out over something stupid. And i was told that if i use them as a reference they will say that I'm unemployable😒. Even tho I was always working other peoples shift and filling in shifts my manager couldn't find anybody to work for. Should I put them on my resume or should I just say I have no experience? I'm completely lost in what to do. I have volunteered but i was told that it wasnt a legal organization or somthing and lost contact with those people. Heeeelp!😭😭😭😭😭
