I think that this song is about a girl he was with and how it didnt work out.
"it makes me miss my friends" - it possibly being the girl, never having time for friends
"you wasted my days" - self explanitory
"building on shaking ground, you cant carry on" - you cant carry on a relationship if one person or the other doesnt want it
"these tides sweep us out of reach" - the tides are the things the keep breaking up the relationship and they are swept out of reach
