ANXIETY CAUSING SICKNESS. Still have!

In the past i have struggled with anxiety after starting high school but in the past year,i have gotten a lot better after getting help and have little to no symptoms of the anxiety i once had. However in recent months, i have had my first proper girlfriend and i am very in love with her. However the problems arise when we spend time together. The morning when i wake up before going to see her,i feel very sick in my stomach which is followed by gagging or usually vomiting. At random points during hanging out with her i can feel this feeling again and it is once again the same after i return home from seeing her, gagging and vomiting. Along with this, i have lost my appetite since starting to date her and especially when with her have a constant feeling of fullness in my stomach. I am fully comfortable and not anxious around my girlfriend as we are very happy together yet i have a feeling that these symptoms may have something to do with the anxiety i may still have thanks for your help
