Struggeling with negative thoughts/guilt and fear

At the beginning of the year myself and my partner found a new place to live and work from, moving there meant breaking our rental contract and not getting back our deposit....so we found another couple to take over our contract....everything went very well and everyone was happy until....

There are many issues with the police and the stories coming out about what happened.....was it just a random robbery gone bad or did Daphna let in some one she knows....a revenge killing (affairs gone bad etc).....you can see much discussion on khmer440.com forums ......

If it was just a random......then that could have been me if we were still living in that house....or my friend who wanted to rent the house then backed out...... also I introduced the couple to the landlord therefore feel guilty.....if they had not moved in this would not have happened....
But if it were a revenge killing (and not the man the police have set up) then it would have happened wherever they lived.....

I have feelings of guilt for introducing the couple to the home.......
..feel guilty for feeling relief that it was not me.....

...fear that it could happen to anyone in any home....even with the razor wire etc (the house was very secure)...

...feeling bad for thinking about it being a revenge killing as that means it would not have been me if we were still living there.

Now my partner is thinking about not going away for a Vipasana meditation as he is worried about leaving me alone. I know he needs a break from work and Vipasana is great for him....I want him to go but at the same time am worried about being alone....our new home is less than 500m from the old place....

Waaaayyy too much going on in my head at the moment.......

....some of our yoga students are also suffering as it is a small town and even if they did not know each other directly there are still connections via nannies, co-workers etc....I want to support them too but still feeling so mixed up myself.

Sorry if this post is a bit odd and not clear......but my head is not clear...
