I know a lot of YT members have been through this too. It is always very difficult to leave our babies when we have to go to work, or college. How many hrs. a day are u going to be gone?
A lot of times they will sleep until the owner comes back, then want to play and be full of energy when you get home. Be ready for that
Keep him in a safe area, and make certain he has plenty of food and water, toys, and place a balnket with your scent on it. This wll give him comfort. I would also start by leaving him for short times right now, then gradully leave home longer each time so he can be use to it.
