Dog Advice

A year ago when I moved out of my moms and into a different state she said take the family dog or she'd give it up for adoption so of course I took her. At that time I was only working a 7:30-4:45... Now I work that and a 6-11 at least 3-4 times a week and a few hours on the weekend. I come home to take her out on break and I between jobs. When I'm off I take her to the dog park and give her loves and play with her. But... She's become so bad. Getting into trash, she recently just destroyed my childhood Bible, she rips up old pictures. She's around 6/7 years old. I don't know what to do, I don't want to get rid of her but I feel so selfish she's locked up in a room all day. What do I do? Please don't hate or judge.
