๐Ÿ๐Ÿ is depressed. How can I help? :(

My boyfriend has been telling me that he couldn't sleep unless he take sleeping pills. He always get to see dead faces and he even told me that he wanted to kill himself just to make it stop..

I am worried.. I don't know what to do..

He is in the military and he is living in the barracks. He's leaving the country in a couple of months but he'll still be away from his family..

Also, he is by himself in the barracks since their ship went underway until August.

I need help.. I want to help him but I don't know howโ€ฆ

Ps, we live in the same city
