Just Found Out I'm Severely Deficient In Protein

I only eat maybe like around 64g of protein on my good days, but usually I probably eat like 32g or less. At 5'9 and weighing 135lbs, apparently I'm supposed to be eating like 96g ideally, especially since I donate plasma. The nurse at Grifols last Friday complained my protein levels in my blood is just barely enough for donating, so was told to consume more protein. I usually don't even get that much calories for someone of my BMI because my mom doesn't cook me enough and food is so fucking expensive the last 6 years.
