Any advice, anyone? I'm really scared . . .

Well, I’m 13 and my parents are in a lot of debt. We received a notice that if we don’t start paying in the rent on time we’ll have to move out by February. Mum says she’ll be able to pay the rent off if she gets her disability allowance, but these things take months to get. She had two knee replacement operations and will probably be having a back operation soon. My Parents are always busy and walk around sad and angry. It started affecting me as now I keep walking around empty inside. I don’t have any friends, but that’s not a problem. I’m not allowed to talk to a counselor as that would mean I’d have to tell them about everything that is happening at home. Even my grades started to go down and the teachers are seriously concerned. I used to be in the top 10 in my entire year (roughly 100 students) but now I’m barely catching up with everyone; I can’t tell them the reason. I really want to cry out to someone, but I don’t have anyone like that. I don’t want to bother my parents and I’m also scared that they will just blow my problems off again. For example, whenever I’d say that I’m sad or lonely to my parents they ignore me or compare it to the problems they have and make me feel stupid; I know they don’t do it on purpose, and I can’t really blame them. Anyone would be like that in their place. My parents don’t speak English well so I have to translate for them often, so I know all about the debts we’re in. I hate translating, since I hear all the bad news. Often, I’d go to a remote place in school at lunch and just cry my eyes out. I can’t talk to anyone, so I’m on the internet instead, since it’s anonymous. I’m really sad and scared. I’m getting more and more weak and tired; I keep oversleeping. I feel so useless, like I can’t do anything. I can’t even get a job because I’m too young.
