I am there with you.... I lost both of my fur babies 3 weeks apart this past December ...... I still hurt. Even as I write this tears well up in my eyes. Yes there is an emptiness do not expect to fill it. Hold fast to the memories of your baby....try to accept that he is happy to be pain free.... You did the most selfless thing you could. Love holds all dear. Time will lessen the hurt but as I know it will take awhile.... My son had a blanket made with Rockys picture on it for me and a pillow of Bullwinkle... His note stated that with these I can snuggle with them any time! I do! I sit and read relax and have them with me. Helps a little

. I also had two beads made that fit my pandora bracelet....one bead for each baby... In those beads are some of the ashes from them. I wear them daily... Has given me peace to have them with me. Silly as I am I often rub them an fell calm. Knowing I have them forever
In a word it sucks! Please know you are loved beyond belief from him....
Wishing you the strength to get thru......
