i'ts been one year since i've met my friend julia and until now sometimes i don't understand her attitude. She was very advance thinking, sometimes she felt liked she was stubbing by others even i know it was not, when we argue something she felt that i am changing, and when i am with other friend she felt that i intended to left her alone even it was not. Sometimes in gathering, someone told me to take picture with other friend, and she was angry again, she felt that i don't like to take pictures with her because i have new friend, something like that..she's acting like child although she's 28 now. She was also very impatient and selfish. She always wants her attention to be with her only. what do you think is her problem? experiencing anxiety or what?

sorry if my english is bad.
