Leaving my dog 9 hours.

Hi everyone! I’m needing some advice on how I should prepare to leave my dog alone for 9 hours since I’m going to be at work. I have a 1.5 year old JRT and I currently live with my family so she has never spent a day alone. My family is going out of town this week and I need to work so she will be left alone for the first time ever for a long period of time. I am pretty nervous because I don’t know how she’ll do. I bought indoor cameras to check on her and also made sure to buy her bones to chew on since I know she’ll get bored. I get an hour lunch so I plan of coming home during my lunch time to take her outside to potty and just spend time with her while I can. Maybe I’m just overthinking it but when you left your dog alone for a long period of time were there any issues? Did they react well? I’m worried she won’t do well and just start going crazy or crying. I plan of leaving tv on for her, lots of toys and things to keep her entertained. I guess I’m just really anxious right now because I know how much she’s used to having a person around and I’m worried she won’t take it well :/
