Answer:
The speaker believes she has earned the right to be in her private space.
Step-by-step explanation:
The speaker refers to the discomfort she endures when she crawls into the raspberry bush (“It drew blood just to get there,” “I was cross- / stitched and beaded by its fat dollmaker’s needles”) but indicates that it is well worth it (“The effort . . . was rewarded / with space, wholly mine”). So she feels that because of her striving and enduring pain, she has won the right to be in that place.
