I am going to offer the obvious, yet not always legal, option: cannabis. It may relax her enough, improve the communication between you guys, lower the threshold for her (so that less work produces more pleasure), and, be otherwise highly therapeutic. It does not work for everybody, but, to me, would be the first option to try (IF LEGAL - I do not want you to risk your careers etc.)

But please do not combine this with thrill seeking in public places. Marijuana is something to be tried on a Friday or a Saturday night when you are at home and not in need of being at work next morning (because it might sedate you, and how much it would sedate you is not predictable).
