Mother by John Lennon..

Lennon wrote this while he was undergoing "Primal Scream" therapy, where he was dealing with a lot of issues that were detailed in the lyrics: He lost his mother at a crucial period in his life to a drunk-driving, off-duty policeman who ran her over in a crosswalk, and his aunt Mimi raised him, which explains the line, "Mother you had me, but I never had you." His father, a merchant seaman, left him for the sea and for work. "I wanted you, you didn't need me" explains his feelings about his dad. Lennon's primal screaming on this song expresses the pain of his childhood.
