My dog (dixie) died 03-07-09 and i cant bring myself to cope with her death. what do i do?

she was truly my best friend always there for me..i loved her soo much i feel like my world has stop and i cant move forward, and it really hits home when i come home and shes not there to greet me at the door or at night shes not beside me sleeping.. i still call out her name... and now when i cry because i miss her shes not here to comfort me at all.. i really dont think i can do this.
