Another Job

ok so I am looking for another job but I love the job I have its just that im only given part time. I work 24hrs a week and i want to make more. My supervisor and I havent talked about me getting more hours. Atleast 32 would be fine for me. I have things like bills that im splitting with my sister since I moved back in with her and its been hell. I would work part time for another job but this job doesnt give me set off days. I maybe off this monday and work the next monday. I just need advice on how to fit another job into my schedule😖😖
