I am so sorry for your loss. I have just recently had to part with my dog of 12 years and I swear he was my brother, my son, my absolute everything. I loved him so much and he loved me back, and I guess that is what drew us together. My parents never really showed me love and affection growing up, but my dog did and I am forever thankful for that. I miss him so very much it has only been a couple of weeks. Some tips I have for you that I practice is to think in a straight path, if that makes sense. I think “yes, my dog is gone. No matter how much it sucks, I have to move forward. I cannot let this bring me down, but I am going to wholly address and accept my emotions and let them out healthily.” I hope this helps and I am sorry again.
