I agree, the funeral may have triggered this response, which very well may be a safty response. Have you thought of counseling? You've been through a tough time, and would probably benefit from an objective outside source.
It may help too to post to Mark Sichel, our resident expert. He's a social worker and a wonderful person to boot. Just a thought...
In any case, know that you have my thoughts and prayers for your well being.
Shalom!
