Hi Hope Floats -- thank you so much for the links! I actually got tears in my eyes reading the symptoms of borderline personality disorder. It sounds so much like my son. The part about one negative comment from another person ruining that woman's entire day, wow.....that really hit home. The last "fit" that my son had was brought on by a few negative words from his sister. He even made the comment, "I was having a great day until she said that!" His reaction to her words was way out of proportion. Scary and sad at the same time!
It sounds like we have a lot in common. I am 48 as well. I believe my son is also depressed, and marijuana is definitely his drug of choice. He spends a lot of time talking about it, and why it should be legal everywhere. Sigh.... :/
I will approach difficult child at a calm time, and see if I can get him to take that survey. Thanks again!
