What does 愛されて mean in this song

Question

I was reading a lyric of a song from an anime called bocchi the rock and there was a line that I didn't really understand what it means

いいな 君は みんなから愛されて 「いいや 僕は ずっと一人きりさ」

What does 愛されて here actually means. I know that it is a passive + te form of the 愛す but I don't know how it functions.

I did search the internet for the translated version of the lyrics but I find two possible translation for that line

Must be nice, to be loved by everyone.
“No such thing, I have always been alone”

and

How lucky would it be, for everyone to have loved you.
"The thing is, I've really been all alone this whole time."

So I really don't know which is the correct translation for 愛されて in this context.

Answer 1

It's part of a longer sentence. The sentence, in a more "prosaic" word order, is:

君はみんなから愛されて、いいな。

How wonderful it is that you're loved by everyone!
You're loved by everyone, and/so I envy you!

Here, 愛されて is functioning as the reason for the corresponding predicate (いいな). In other words, it's the te-form (て-form) for Cause or Reason.

Also note that いいな, いいなぁ and so on often express the feeling of envy.
