HELP! urgent! my new cubicle pal at work hates me!!!!?

Yesterday I got a new cubicle pal named Pam Goldstein to share my cubby with. After showing her around our cubby and giving her a grained tour of our desks area, i sat back down at my chairs to finish my workings. All day i have tried to be very friendlys to pam, I have offered her half of my egg salad sandwich and a juice packette which she rudely declined, then i asked her if she also uses super maxi pads with wings because i keep a larged supply in my drawer which i told her she could have permissions to use, then i even asked her if she wanted to go take a potty break together and she was ignoring me. Then i asked if she would mind if i let out ges because i was having violent stomach gas troubles due to my spiced egg salad and she got up and went into our boss's officed. when she came back she began clearing her cubby area and didnt say a word to me. today my boss wants to see me after works and i am very worrieds, what should i dos?
