Help please!!!

My boyfriend is currently going through a lot right now. He says he’s feeling anxious and is having a hard time because of covid and feels really low in mood because he’s social distancing. I can tell that he’s getting more and more down as the days continue. I want to support him more and help him feel better. It makes me so sad to see him this way.

He’s usually always there for me because I have GAD so he’s, I guess you could say it, the more emotionally stable one and now that the tables have turned a bit I want to support him as much as he’s been supporting me. Does anybody have any experience with this? How can I help him

Thank you!
