How Depression Is Affecting My Relationship I Guess

Hi everyone, i was wondering if anyone has some tips or advice. I just found out i have depression recently, and it's really affecting my relationship with my boyfriend. We've been together for about a year now, and having depression makes me overthink everything so much that i guess it's tough on him too. He keeps telling me things are fine and that i'll feel better eventually, but honestly i struggle to be happy or present in the moment. It feels like i'm only halfway there emotionally. Any suggestions?
