It sounds like the lead singer was reminiscing of a past relationship with an emotionally distant person. Reading between the lines, it sounds like the relationship ended because he/she couldn't just let their emotional walls down enough to be loved, and the frontman had enough and left, implied by the line "I missed you but then the moment was gone". This suggests that, while it was very painful to leave, it had to be done.
The line "now everyone is gone, let it slip away", seems to imply that a part of the frontman may have felt guilty about leaving because this person had alienated everyone he/she loved, but reminded himself that it is his/her problem, not the frontman's, and in the end, his mental health was more important. The song also seems to imply that he's run into this person, years after the fact, and found nothing's changed.
