Cat owners. I need some help with a traumatized kitty. [View All]

Ok, my cat has been thru the trauma of me leaving my boyfriend (major ordeal) and moving to a really tiny place that's less than half the size of our old place in the last month. I am sure she misses him, they always played. (I certainly don't lol)

but here's the problem:

She is driving me BATSHIT INSANE. About 4 or 5 times a day she is in my face or climbing my back and wants my undivided attention. I play with her for 20 minutes or so but it's not working. She's somehow forgotten how to play alone. This goes on for HOURS. I work from home so this is becoming a serious issue, besides the fact my back is starting to look like freddie krueger visted me in my sleep (and yes I keep her claws trimmed). I can't get anything done. She's also started biting! She never did that before!

She's 2 years old and has always lived with 2 people until now. She's an only kitty and an indoor cat.

Does anybody know anything I can do....before I lose my mind!
