Boyfriend help

I love this guy so much, we’ve been dating more than 2 months (we’ve known each other for two years before) right now he’s been struggling with depression and anxiety but he doesn’t want to talk to an adult, a parent, or to his siblings about it. I’m the only one he tells this stuff too, but I’m not a counselor. Yes, u suffer from anxiety and Depression, but I’ve run out of things to say to him to reassure him. Can anyone help me out with other things to say or what to do?
