Myfriend bothers me alot help?

well i have this friend and she is really kind and soft but the prob is dat she gets in my nerves alot and i cant like enjoy unless i scream at her. she is kind but she worries too much of the smallest and useless stuff that is possibly ignored like when she gets her perod she asks me if therer is a blood stain on her pants, or if she is fat. she is not fat and she asks me every minute about it. every second annoying question after another. a million. stuff that she knows and asks over and over also. on the phone she basicly talk bout her probs only and basicly ignores my probs i ask her,she expects me to fix her problems. she calls me 24/7 nonstop even wen im at a friends house and i tell her im gonna call her later. but calls my a minue later to ask my a small dumb question she shud know. i cnt take it wat do i do???
