I am so scared for my sister! i don't know who she is any more

Hello Everyone.
I am worried for my sister that had the Fobi pouch done about 2 months ago. She had the surgery with Dr.Fobi and everything seemed to be okay. But she is now having a hard time dealing with the after effect with the surgery. She says she wants to have it reserved, and the doctors say they can not do anything for her until 6 month after surgery. This surgery has changed he so much and makes me very worried for her because my sister was an active women that has gone from active to non coherent. All she can say is "she wants to feel herself again" . She has been to the doctors at least once a week to make sure everything is okay, and they say nothing is wrong. She takes her vitamins and her blood is okay, but mentally I feel we are losing her. I can't understand any of this- I had the same surgery April 08 with Dr.Fobi too and I do not understand what she is feeling I had much success with losing 115lbs. Some one help me help my sister I really don't know where to start to get her help with the reversal because no one wants to help! some one with answers please help us!
Thank you Ana

I was VERY,VERY, VERY fatigued the first six months orso. I could barely stand up without getting dizzy, but I managed through somehow. The low energy / lethargy lasted for over a year. Only now am I beginning to see some energy again. But, I'm thin and the surgery was SOOOO worth it.

Thank you!
they are now saying she had a mild stoke, but i really don't think that had nothing to to do with the surgery. I also have had the surgery and i am fine.. i think also it was well worth it but i want to see if any one felt like her so i could understand what is happening to her is normal for some people.
