Vision!

Soo my baby is almost 3 weeks old and I get no sleep through the night I only get sleep early in the day bc that’s when he will sleep the best. He’s very fussy at night. Last night I had a huge headache bc I couldn’t get any sleep and it’s been like this every night! Well today I woke up with weird vision problems. Everything I look at has like a black shadow and looks like flashes of lights and I’m wondering if anyone gets this from lack of sleep with their newborn? I was struggling to make a sandwich bc I just felt like I couldn’t see it good
