stillstuckcruz: You should think very carefully before doing anything. However, a couple of points... Do you still live with your parents? I'm not sure, but from your comment about PDFs being seen by your family, I assume that you probably live with them... Or that they're too much of Facebook addicts to get off the computer for a couple hours to visit you. If you do live with them, make sure you have an escape plan. Do you have any worldly relatives you could go live with for a while? Maybe some friends? You don't want them to throw you helpless into the street, which is always a possibility.
On the subject of the computer, I'd suggest grabbing a program called TrueCrypt. It's open source. You can install it on a flash drive, and it allows you to encrypt stuff you don't want peope to see on a fake hard drive that looks like a file. Put all your files on there, but make sure to not lose your password, as it's extremely secure and there is no way to break the encryption (with a strong enough password). As long as you don't leave CoC open, or leave the encrypted "hard drive" mounted, there is realistically no way they can find your files.
