What am I feeling? *help*

I haven’t ever felt this way. I very much adore and cherish my dom but I feel like I need to be in constant contact with him. If I don’t get a response to a message after so much time, I can’t stop my mind from spiraling into all of these negative thoughts about how he doesn’t want me and that I’ve upset him. It makes me so anxious but I feel like I also can’t do anything else.

He’s very clear about his intentions with me, he’s very supportive of my emotions, he has me write in a journal and sends me pictures and voice memos for when I’m feeling like this, but I don’t know how to make it stop. It’s like I am craving him and his attention 24 hours of the day.

I don’t want to mess up a good thing with my own brokenness but I also don’t know how to approach a solution because I don’t know what’s causing me to act so “crazy.”

For context I am an extremely independent woman, I have a successful career (that I can hardly focus on right now), I have always occupied myself in the past. But over the last few weeks.. idk.
