lost my cat whilst away at university

pretty much what it says. i got a call from home about an hour ago telling me our cat had died. i just can’t get over how when i left i felt like i didn’t say goodbye to her properly and not even being able to see her now just makes everything feel so unreal. my mind can’t comprehend the fact that when i get home she won’t come and lay on me whilst i sit on the sofa or climb in through my window at night. she was so loving and i felt sometimes like she was the only one who understood me and losing her feels like losing everything. i just can’t get over the fact the last photo i have of her was one sent to me instead of one i took.
