Aggressive 4 Month Old German Shepherd

We have a 4 month old female german shepherd pup which during the day Monday-Friday left alone for around 7 1/2 hours. When we get home she just cries really loud, tosses her head and bites.

I know it is hard for her being a lone but how do I get her to calm down. She is just so aggressive when we get home and also she doesn't listen to anything I say. She just barks at me. I used all kinds of techniques
