Here's my interpreation. Sometimes the worse life gets, the harder it also gets to recover (like anything abandoned and aging - it gets rusty). You blame people for not being there, and then when there's noone left to blame, there's nobody left. The people who have associated with the main character here have been selfish/uncaring/intolerant, and unfortunaately it's a shame because it's their loss for not being there and missing out on someone with a lot to offer.
