If I may jump in....... your thoughts and feelings are so very very normal.. I think we all go through it...the pain of what is lost...and to be honest, it is good that you are allowing the pain to happen. Go through it, for it is a very important part of healing.
One day (you can't even imagine that now..) the pain turns into something different... it turns into a memory, that you will think back upon with great fondness, and that will be when it has gotten to the place it should be...and yes sweety, it takes time, time, time, but you WILL get there.
Take care xxxx
