Stressed lover

So my boyfriend is going through a lot. He's 19 and still living at home but his family practically ignored his and is basically hunting for him to move out. So he's frantically trying to fix his car and move out. He's a barista and opens a lot (3 AM SHIFT) and loses a lot of sleep. He's been super overwhelmed and I've tried to be there for him but it's hard because we are long distance and I've been a bit clingy. Now he's pushing me away because I think he's depressed and I don't know what to do. Help me please. I love him so much
