The term 'regardest' indicates that the speaker's view of God is one of constant closeness.
Explanation:
In the poem, author Anne Bradstreet employs the term "regard" in a formal sense, meaning "to observe". She asserts that God has witnessed her suffering, struggles, and adversities, and in the following lines, she continues to recount how God witnessed her in distress and provided healing when she needed it most.
As a result, she conveys a sense that God has been constantly watching over her. This poem exemplifies the faith and loyalty the author holds towards God. Having such faith indeed fosters significant positive energy.
