At 6 weeks old this is a medical emergency, I would take the pup to a veterinarian, the closest walk-in emergency animal clinic, now. I would not waste time on the internet.
Best of luck

PS: If financial concerns are an issue, explain that to the clinic and they will tell you your options. The most important thing is to get that pup seen by a veterinarian ASAP.
If you are under 18, alert a parent or a responsible adult to the situation immediately.
