I agree with the people who said you need to distance yourself from your in-laws, because they are not helping you heal. I've had to pull away from both my sisters, because I don't feel that I can talk to them about my dog or our father (who died about a month apart) without feeling judged or attacked. It's hard, but you have to look out for yourself.

Please look into local support groups, and try to find a support group or pet loss counselor as well. You might try the local SPCA to see if they off grief counseling, or search online for a national 800 number.

I'll keep you in my thoughts.
