Living with SO while having anxiety

What's it like living with your SO & having an anxiety disorder? I have GAD & i suffer a lot of stomach problems & I've talked about moving in with my SO but the thought of it makes me anxious like I'm gonna feel uncomfortable & i guess I'm just insecure about my anxiety around him. We've been together for over 2 yrs but almost a year ago my anxiety came back & been dealing with it ever since. I'm just wondering if sooner or later I'm gonna be comfortable around him...
