Maybe these,
"Nostalgia"
We have all made memories with family ,friends, and others. Across time, things have changed. Family members grew and died, friends moved or abandon you, and you grow.
"Death"
Death is inevitable, like change. Some die old and had a long, great life, while others...die really young, still having opprotunities ahead of them.

Alright, I got a suggestion, seein as I now got an idea from readin it.
1: 'Loss'.
Can basically be about losing your way in life, or basically having no clue on what to do, even when you desperately search for an answer.
2: 'Change'
Change.. is inevitable. Some are prepared, some are not, some are oblivious. Yet the thought about it can haunt a few.
