I can’t seem to move past this

I posted here a while ago about being sexually assaulted in 4th grade and how I recently remembered everything. Well I gave this guy my number and oh my god is he sweet he talks to me like he really cares and walks me to my car. I just get butterflies thinking about him at all but I can’t stop being terrified of what might happen we have a date Saturday and I feel like I’m thinking like a crazy person. I can’t get the idea out of my head that something’s going to happen. It’s like I’m fighting myself everyday just to keep it going. How do I stop this?? I’m working on getting a therapist but it won’t happen before our date what should I do??
