Hi everybody!

I am facing a rather serious problem with my younger sister. She is 30 years old and married.

She was a bright child but over the years she has become rather friendless and insecure. She also seems to have a new problem everyday. She shares these problems with me down to the most intimate details and expects me to listen to her. If I don’t stop whatever I am doing and give her full attention whenever she demands then she calls me 'uncaring' and 'lacking empathy'.

I try my best to accomodate her. But after listening to her, literally for hours, if I give her my opinion or advice on the issue at hand she snaps at me, and very rudely says something like 'how I live my life is none of your business/ keep your opinion to yourself'. I have been very hurt by her comments quite often but still I chose to look past it as she is family.

Stuff hit the fan this morning when she came over and She then went on a tirade about how he will 'learn eventually' (he is 29) and how I never see his good points. I mean did she expect me to sing peans after learning that her husband treated her like this?

I finally got sick of the whole thing. I told her if she did not like me commenting on her personal life then maybe she should stop talking to me about it.

Now she is acting like the injured party and telling me 'Oh so that is how you want things to be between us'. I am so confused.

I am also a little upset with her lifestyle. She lives with our mother and is dependent on her financially. She only lives with her husband during weekends and he doesn't take care of any of her expenses. My sister sleeps all day, everyday, waking up only to eat the meals someone else has prepared for her. She is morbidly obese and all doctors have advised her to get some exercise. She is also addicted to online shopping. But the moment I try to intervene, out come the colourful insults. As kids I was verg close to her, almost like a third parent. But now I seriously struggle to maintain a decent relationship with her.

She has seen a psychiatrist and was diagnosed with OCD. She is under medication for it.

I shall be very grateful if you could offer any insight into the situation, as I am at my wit's end. If I can understand her problem maybe I will find a way to deal with her. Please help?
