advice please

So my man works 3-11 so I decided to get a job to keep me occupied while he was at work. I found a job but my training is during the day from like 7am-3pm. My man is a coal miner and doesn't get home sometimes till like 2:30am so we only see each other for like a hour and go to bed I sleep for like 2 hours and go to work. This job was suppose to make things easier on me and all it's doing is making me extremely depressed!!!!!!
