OK, she has forced her way into your house now you send her the house rules in writing so she cnnot say she wasn't warned. Include not smoking in the house or near doors or windows and no alchol of any sort on the premises. She will also help around the house as you are not up to hotel guests.
Then let her know if she cannot agree to these conditions then she needs to stay elsewhere.

Don't let her stress you out, you may find you will need to go on a few walks for some fresh air
