The answer is "to have lived". "I really miss being there." is indicative that the narrator/speaker no longer lives there. That makes it past tense.
I miss these girls.
is the correct one.
Today was the day ' m going to be used and not be in storage' as I thought to myself wondering why I was never used. It was dark of course but I wasn't the only 45 pound weights. There were others some we're big and small but still leaving. As I hear someone slowly opening the door knob, I can hear the figures talking from the other side of the door saying " Hey Kev want me to get the weights, cause many people have been using them and the other broke." As you were excited about being pick I had remembered 'broke what how' but somehow that didn't really matter in the moment. I could here footsteps approaching me and hearing the sound of a box cutter slowly open. Then hearing the satisfying noise of the box opening. Ever so slightly I could see a light peer through the bubble wrap and styrofoam. I saw it light it wasn't warm but comforting in a way. As the figure picked me up I could hear the noise of people talking, metal clanking against each other. The music and seeing lots of lights was very satisfying. 'Im here am here I made it finally' you could only be happy and nothing more. As the days had gone by I was being used by many figures it was delightful to be finally be useful.
