what is wrong with me?

My bf and I have been together for over a year and recently things have been weird. Since we’ve both been busy we don’t really talk or respond to each other as much as we used to. We’re not fighting or anything negative it just sucks. He’s busier then I am and I just don’t want to be a burden. My depression keeps hitting new lows and not being able to go to therapy doesn’t help. I figure that by not bringing up these negative emotions it will make him less stressed. All I do is cry and I don’t need him worrying more then he already does.
