just not happy

Being pregnant should be a time of happiness and all other good emotions which I was at first but now I'm just a crying mess. My boyfriend leaves 7 in the morning and gets home at like midnight or later.. I'm alone all day and have no one to talk to or anything. I work part time because I go to school full time but most of it is online. I'm just tired of being alone and eating breakfast lunch and dinner alone. It's just depressing. Anyone else feeling lonely and depressed in their pregnancy ?
