Low sex drive

So I’ve always had a lower sex drive until I met my boyfriend. We always talked about how each of us had lower sex drives well ours was always really high when we first started dating. We’ve been together 4 months now and mine is almost completely gone while his is still higher. Now idk what to do. He gets bummed out by it all the time which causes me to get bummed. Me having a lower sex drive has always been an issue in my relationships and I can’t stand it. I talked to my doctor but she didn’t really say anything about it. I have depression and anxiety so I know that doesn’t help, but are there any ways to try and get it up? I’m tired of this.
