Small loan or KfW student loan?

I'm currently in a pretty bad situation. Unfortunately, I only receive €550 in student loans (BAföG) plus €250 in child benefit per month. Currently, my rent alone is €500, and after deducting my other fixed costs, I'm left with about €200 a month. Because I had a few bills at the beginning of the year, I always slip into overdraft by the middle of the month and end up with a €400 balance. My expenses, however, always remain the same.

I'm moving into a student residence hall soon, which means I'll have to pay less rent. Unfortunately, since I won't be able to work next semester because I'm working for a solar installation company and can't combine my work hours with my seminars and lectures, money is getting increasingly tight.

All in all, I'm getting by just fine with the money I have. I just want to get out of the overdraft so I don't have to keep paying such high interest rates. It just doesn't feel good to go into the overdraft every month, and the overdraft can be canceled. And my parents don't have the means to continue supporting me financially.

Back to my question: I've been considering taking out a small loan of €1,000 to get out of my overdraft and refinance. Then I'll pay €20-30 a month, but I'll generally have more financial freedom. Are online loan providers like auxmoney recommended or not?

The other option would be the KfW student loan, where I could get €200-300 paid out monthly. However, the amount continues to decrease due to the direct interest payments.

Of course, I also hope to find a better student job soon, where the hours are more flexible. But right now, I just don't want to worry every month about not being able to afford my food anymore.

I would really appreciate some advice or opinions.
