You don't say what your marital/living arrangements are - so a context for giving advice is missing and advice will be limited.
As an elder, ex-Bethelite (and more), I will generally advise the following:
First, Shut the F**k up! Don't say anything that could get you in trouble. If you have said too much already, claim depression! You were just feeling down and will go to a doctor to get help.
Secondly, Do something you can cite later. Drive your dear wife to a Sunday meeting. Bug out during the Watchtower Study, if you need to do so. Cite a 'phone call emergency'. Come back and take her home. .
If confronted, be pleasant and lie your a$$ off. The Governing Body? The Faithful Slave? A great bunch of guys. I'm sure their jobs must be difficult.
If the above proves difficult to bear, do it anyway, for the present moment. Give yourself enough time to figure out what you really want and how to obtain it.
