Which is the best paraphrase of romeo’s lines?

your love and concern are making me feel even worse.
your love and concern are the source of my sadness.
your love and concern are a big surprise to me.
your love and concern are lessening my own grief.

Are these Romeo's lines you are referring to?

Which thou wilt propagate to have it press'd
With more of thine: this love that thou hast shown
Doth add more grief to too much of mine own.

If so, I believe the correct answer is the first one - Your love and concern are making me feel even worse. He says in the excerpt that her love adds more grief to that which he already has a lot of, which makes the first sentence the only possible option here.
