The other suggestions here are great as well, I just wanted to add that you should avoid alcohol. It wasn’t until a psychiatrist suggested it that I realized “holy crap”, after I drink I am more anxious in general for 2-3 days. For me at least it doesn’t seem to matter how much I drink, even a couple glasses of wine with dinner will make me more anxious the next day, but it does seem to scale up with intake. YMMV. Edit: as another comment suggested, CBT would very likely help, particularly if you’re nervous about certain things and there’s no “real” reason for it. If there’s a specific reason behind the anxiety (like worrying about a language barrier with the dentist), then CBT probably wouldn’t be my first priority.
