Should I ask?

I'm indeptendant and have never had to borrow or asked for money from anyone not even my from my parents nor be in a situation where I needed to borrow. But now I'm in a situation where I need to borrow and I'm too scared to ask my mum if I could borrow her money. Should I ask? Would it be wrong to ask her? I know I get lectures off her if I did. What should I do?
