Need help/advice as an international student

Hi everyone! I know this is silly and I swear I’m going to quit my other job this week but I need advice. I’m working 2 jobs as an international student both part time and casual.

In my main job, I’m part time. They give me the hours I need max but it only helps me pay my tuition and rent. The reason I had to take on another job is so that I have extra like to buy groceries or cover my living expenses.

But I want to stop because I’m afraid it will affect my visa applications in the future. However, I know I’ll have a hard time living for a while. My question would be is do you think I should just switch to casual on my main job (this is the job related to the course I’m currently studying) so that I could keep both of my jobs or just let the casual job go?

I apologise if I’m asking for advice here. I don’t have any friends here and I don’t think most of my colleagues at work would understand my situation rn.
