If your girlfriend works the night shift, will you not text her for fear of disturbing her rest?

Just send her one or two, but the content must be more, let her see that you are working hard and won't bother her. Tell her that if you need anything, you must come to me. I will wait for your call or text message at any time to let her know how important she is to you. Finally, tell her not to bother you and add some sweet words.
