site was hacked and now my posts are messed up

They might have hacked your index.php file.

I looked at your html source and it’s missing both the header and footer info (no style sheet, etc.)

Thank you!
Sorry but I am new to this. How do I go about fixing this?

If you have FTP and a backup of your files, you can upload a backup copy of index.php to replace the current version of index.php.

Ok so I tried this 2 times and it did not work… any other suggestions?

Look at header.php in your theme; there is lots of html code out of place and that is what is throwing your sidebar out of place. Do you a fresh copy of your theme – AutumnScene – to upload? If that theme was customedited, you’re going to have to try and compare the php/html code between the original and yoir custom theme to work it out.
