I'm so sorry for the loss of your Jasper. There is nothing any of us can say to take the pain away but just know you are not alone. We are all here missing someone we loved with all our hearts. It is hard when your family doesn't understand. My family doesn't either and I feel like it has compounded the pain.
I've been doing a lot of reading and listening to podcasts and the big thing I keep hearing is that you need to feel all of the feelings. As hard as it is we need to let ourselves feel the pain and the grief and not try to bury or avoid the feelings. If you need to cry then cry. If you need to scream then scream. We all grieve in our own way and there is no right or wrong way to do it and there is no time frame. I'm told that one day we will get to the point of being able to think of the memories and smile rather than cry. It's hard to imagine right now but one day that day will come. Just take care of yourself the best you can.
I miss you every minute of every day, my sweet baby Jasmine.
