The "unique or single effect" that Poe is attempting to express in this passage is B. SORROW.
It shows how she has waited for a long time to be loved by the person she has loved. That person is the "me" in the poem.
Many and many a year ago depicts a very long time of unrequited love or a one-sided love at stated by the text "no other thought than to love and be loved by me".
I would say that it is quite important to recognize and acknowledge that everyone in the world has common life experiences that are positive and negative because while it might be great to stay by ourselves and be alone for a while and sit with our thoughts if we had a negative experience, it's also great to go out there in the world and find someone who went through something similar because it can make one feel so much better to have someone who truly understands their pain or the difficult emotions that they're feelings/going through at the moment. And if it's a positive experience, the same principle applies. Maybe you want to go out and find someone who knows that excitement that you're feeling or someone who knows how much work you put in to get to that place you're at now.
Hope this helps :>
