Turning essay writing from anxiety into something manageable

After another late-night study session I’m sitting here staring at a half-finished essay and a pile of coffee cups. I keep getting stuck between wanting everything to sound “academic” and just writing like a normal person. In school I could wing it, but now in college the grading rubrics are way stricter and I overthink every paragraph. How do you plan and write without turning it into a huge anxiety project every single time?
