I need some relationship advice (no negative post!)

So I've been with my boyfriend for nearly a year annd we also been long distance 9 months out of the 11 months we been together.....anyways my boyfriend as been stressed out not only from not seeing me often all the time but he works a 12 hours shift either during the day or night time and lastly he seems be depressed because where he's living now it's at home with his parent in the middle of nowhere ( and that's the big reason we can't see each other often). He's hasn't been talking to me often like he use to for a couples of days and I never did anything to get him angry or upset lately and all I wanna do is help him not stress out too much about us or his work🙁 should I just give him some space or should I try to talk to him? What should I do?  FYI: Please don't put no negative post about long distance relationship are bullshit and they don't work 😑 I actually am in love with my bf and he feels the same way about me despite I don't see him often.
