[Shick]

1. only if the sentence is expanding on something previously stated.
2. correct
3. doesn't make sense in general change the whole sentence
4. "i loved the piece of writing you recently posted on facebook" facebook is a company, one word
5. take out because and separate them with a semicolon (

Suggestions: it would be better to say (1) "...such a life...", (3) "...as I used to." (4) "...you recently posted...".

In (2), I don't understand "instinctual". Also, in the way the sentence is written, the first (subordinate) clause refers to the song, and not to "you", which I think should be the intention. It would be better to start "Even though I could not understand the lyrics, the song...".

Quite a good effort though.
