First Time Anxiety bc of my boyfriend

I have been with my boyfriend for 7 months. I love him so much. We spend every single day together because we can’t get enough of each other. Never in my life have I had severe anxiety or anything close to a panic attack. However, the last two weeks I have had two full blown panic attacks where i am sweating and crying and my chest is tightening and I’m hyperventilating. Both times have been triggered by the thought of my boyfriend driving home for the night (like he always does) and getting in an accident and getting hurt. I get so anxious at the thought of anything bad happening to him that I can’t control. What do I do? Has anyone else experienced this? I feel crazy. both times my boyfriend has held me and talked me through the moment trying to distract me and get me to talk about other things Help I feel like i’m crazy
