Anxiety causing no real action


When doing models I often find the feeling generated is anxiety (looking forward to feeling it this month and not resisting it). Most of the time I can’t think of an action caused by the anxiety except to perseverate on the the thought. The only result I come up with is wasted time. Is it common/acceptable for the action to be perseverating with no real result except wasted time? Or should i keep trying to think of other actions and subsequent results from the anxiety? I feel like the action and result should be more tangible. Perhaps my action is resist the feeling but I’ve gotten much better about not buffering with food……so still main outcome even if resisting is just thinking about how it sucks to feel anxious.
