Would you buy a new mattress? 😫

I had my mom stay the night last night since it was Mother’s Day. I had her sleep in my bed. Well.. she peed in my bed. It happens and all that, but my mattress is soaked. And it’s a pillow top mattress so I can’t flip it over or anything. What do I do?? I can’t really afford a new mattress. I only have $200 in my bank account. I could use my credit card but I am doing a lot of home repairs right now so I’m already using it for a lot. Please help ughh I don’t know what to do. I even had a mattress protector on. My mom had been drinking so I think that’s part of why she peed in her sleep. I’m not mad at her but I’m a little frustrated with what to do and she’s taking it personally
