Regardless you are trying to avoid a trigger by leaving. Exposure is usually the best way to overcome anxiety.

On another note I have something that can help nausa related to anxiety.
5-7 slices of ginger
Half a lemon
some cinnamon (not a lot)
Boil in water for 15 minutes
Add honey to taste.

You have to drink it while its warm. Another member sent it to me and its helped. I don't mean to be an asshole either. Sorry about that.
