I have just seen your post. I am so sorry. You must miss Mishu with all your heart and soul.
The grief with the loss of a loved one is different for everyone, but when they have first gone, what everyone feels is tremendous devastation. It is not depression. It is Grief. It is not an illness, to be got over as quickly as possible, and it's not something with any instant cure. Neither is it irrational or crazy, or selfish, or anything else. It is a natural response to the sudden absence of someone you love very much....whether that 'someone' is dog or cat-shaped, or human or Elephant-shaped -that doesn't matter.
Grief is something that has no time limit, and even though it slowly does change, so life becomes possible to live again, there is always an aching gap in our lives where that special loved one always was. That doesn't ever go away. But it is true that life becomes more livable in time. And there are many times it's possible to smile and have some happy memories, and the love becomes a great blessing instead of an agony as it is when they have just gone.
We are all (animals and humans) body, and Soul. The body isn't immortal and it dies. The Soul doesn't die, and goes to Spirit. I think it is basically the Soul of our loved ones which we bond with and love endlessly, and we think that has gone -but it hasn't. Only the body has gone.
The Soul lives on, and it is very real. My dog showed me that.
I have heard a lot about animal reincarnation, but don't really know from personal experience. I know animals have Souls -from personal experience. And I know they live on in Spirit in a very real way, and often come back to visit us -from personal experience.
But what my dog Misty has shown me is that she will wait for me there until I cross over too.
In the meantime she will visit whenever she can, and I often do sense her love crossing to me. It really is very beautiful. I wish it could happen more often. I would like it to be every day -but that is a bit selfish of me!
It has only been a very short time since your Mishu left. So you will feel grief very strongly, and that is natural. But don't forget Mishu still does love you very much, and is still very much alive in Spirit (which is a living real thing)
Mishu is a lovely sweet girl. Her pictures are so beautiful!
