How do I fix a sudden leak under my kitchen sink if I can’t get a plumber to my home immediately?

So I’m kinda freaking out right now — I walked into my kitchen this morning and found a little puddle forming under the sink, and it’s only getting worse. Of course, every plumber in town is booked solid for days, and I’m over here with a towel army trying to keep the water from marching across my floor. I’m not super handy, but I’m willing to poke around if it means stopping the drip before it turns into a full‑on disaster. Anyone have tips, quick fixes, or magic spells to hold me over until a pro can get here?
