Why is college so expensive?

I am so stressed of applying to colleges and financial aid, I have so many things stopping me from applying for aid and now I think my parents will have to pay for everything. I told my dad and he got mad but he and my mom are the ones to blame. Their paper work is all messed up and so are their taxes. I have been so stressed and crying for so long I am so tired and restless. I keep having panic attacks and feel like screaming so loud, I feel like running and I keep thinking of making the worse decisions ever. I am so afraid right now, I have no one and I'm going through so many emotions it is scaring me. I feel so alone and everything is so overwhelming. I really want someone to hug me and say to relax but everything is making me fidgety. I feel like I'm going to die or something bad will happen I don't know what to do. I feel like I'm going crazy, I am so terrified. I am so afraid.
