Feeling very sad since selling great grandparents house

Im feeling really sad today we finished moving every thing out of my great grandparents house since it has been sold and left for the very last time even though my great grandparents are no longer here with us its still sad because almost all of us have lived in the house at one point or another plus the house had been in the family for 60 years the thing that i will miss the most is my great grandpas workshop i could just go sit in there for a few hours just looking in there and thinking about him im really going to miss being able to go there
