Yes Calista+12, I too have wondered at times. I do believe it's a natural reaction because of our past.
For the most part, those you meet here are all very sincere and very caring. You will on occassion get a few who are not so honest and like to play games. Some even "take on" a diagnosis just for the attention, or will deliberatly stir stuff up and sit back and laugh.
Trust your gut.
