Hopeless

I am just so hopeless after my ultrasound today that i really dont know what to do. Last usg on 1st of june baby was in 19th percentile at 32w4d with baby weight at 1625 gms (3.58 lbs). Doc said everything is working fine like placenta and blood flow. Afi was also normal so doc suggested me to pack on the proteins. After eating relentlessly for like a month i had my growth scan today and baby is measuring at 5.11 lbs at 36w5d. I really dont know what i am doing wrong and just feel so hopeless as if my body is failing my baby. Doc is inducing me at 38 weeks.
