I think you people think too much personal things into it, yet you are right on some parts, but I think this song can mean a lot of things - including the things you said. I think it is meant to mean a lot of things.
In my opinion it says:
You will encounter both shit and good things, shit may come in a bigger dose than good things, but you should fight. People and things will likely to slip away, but try to hold onto them. Your loved ones can get you through this, but you might except some kindness from the wrong person.
