I work Monday through Friday, 2p.m. to 6 p.m

But this week he works Monday from 3 p.m. to 3 a.m. plus his normal weekend shifts. He wanted to work it because on the 18th of May, his mom might come over to visit, but its like 10% sure she will. And he wanted the day off.
I tried to tell him to work 6 hours today and 6 hours tomorrow. But I understand he wants one day off. All of my friends are 7-8 hours away. I am just gosh begotten lonely. He told me to make friends, and entertain myself. He gave me his car and told me if I wanted money, but its not that. I feel that I don't see him enough. It sucks coming home from work to an empty house.
I also have depression and PTSD, and I just can't stand this overhelming feeling of lonliness. I just wish I wasn't so alone.
Any ideas?
BTW we live together if you didn't assume it.
