It must be tough to go from having what you consider a "nice" home to one that you feel is run-down and shabby. Considering your parents' separation, it must be hard not to take your father's leaving and your change in financial "status" as symbolic of your worth, but many families who experience divorce or separation see their standard of living decline. I hope you are finding the support you need in dealing with the feelings that are bound to come up when parents split. If not, you may find some comfort in talking to your school counselor.

But back to the problem you wrote in about--your physical environment. For most, home equals comfort, so I can see how having a less-than-ideal place to come home to every day, would compound your feelings of sadness and isolation. The good news is that there may be a way for you to "kill two birds with one stone," so to speak. Why not organize a project to make improvements to your new home? Engage your mother and your siblings--if you have them--in the home improvement project. It's likely that other members of your family are having similar feelings and such an undertaking may help you talk them out with each other and feel closer in the face of all of this change. The project will not only give you something positive to focus on, but will likely make you feel less helpless in the situation.
