Are you apathetic to the situation or have you taken care of things? Like do you have another job now? Have you found a new apartment? A new band? If you have moved on without dwelling on/getting too upset about the past, maybe that's a good thing. If you haven't taken care of these things and just sit around looking at a wall or something all day, there probably is a problem. You would best know if you are repressing feelings though, I'm just guessing at this stuff.
