My boyfriend is leaving for a week

So I moved in with my boyfriend April last year. He’s going to a festival in March for a week I can’t go because of work so I’m staying here in the house. I never been alone. I haven’t stayed alone in a house before. We do live in a condo complex and we got security cameras. I just don’t know what I’m going to be doing after work. It takes me a while to fall asleep if he’s not in bed with me. How can I fall asleep easily whenever he’s not here? What are some things I can do to not be afraid of being alone or to distract myself?
