It is understandable that you feel the way you do you have lost one of the loves of your life and it will take quite a while to ajust, we dont get over a loss but learn how to deal with it and believe it or not you will in time be able to think and talk about Buddy and laugh at the goofy things he has done and smile about the amazing time you had with him and that how lucky you were to have had him in your life. Stay strong and try to make an extra fuss of Tank as id say he is picking up on your sorrow an somehow my think its down to him that you feel this way.
God be with you and grant you peace.
