Anxiety Destroying Sex w Boyfriend

So I have anxiety and depression and I take medicine for it, but lately I just don’t feel like it’s working anymore.

So sometimes my boyfriend has a stronger sex drive than me and it makes for a terrible interaction. Like I am so not wanting to do anything and he is so wanting to. I try to be like “I’m not in the mood” but then I feel like he thinks it’s like he can get me in the mood. And he could if he really put the effort in like gave me time to decompress from my hectic life and calm tf down before jumping my pants. I feel bad because I full on told him to stop because I couldn’t because I wasn’t in the mood as he was eating me out. I just couldn’t handle it. I was so not in the mood and I was just too stressed and felt that I was internally imploding.

He doesn’t understand when I’m stressed like this I need extra steps to “get in the mood” I don’t know what to do I’m honestly so tired of this happening and talking about it. But I just want it to be chill if I’m not in the mood, I’m not in the mood. End of story. Not having to turn him down over and over until he gets upset and says things like “wow I’ve never had that happen” “wtf dude” “okay, yeah, whatever”

I know I’m like slapping his confidence when I’m not in the mood, especially in this instance because I literally made him stop while he was eating me out. But, Christ I don’t know what else to do. My anxiety doesn’t let me calm down at the flip of a switch.
