mood changes

I am having a rough time with mood swings. Why is it that someone else's behavior can have such an impact on me? Or is it the med change? I am definitely more vulnerable to changes in my environment since going off the Topamax. I didn't sleep last night because my best friend was in a car accident and had alcohol on her breath. She spent the night and most of the morning in jail. I was a wreck just thinking about how scared and insecure she must feel. The thing that sucks is that it was the beginning of her birthday "weekend" that her husband had planned. Four couples coming into town to celebrate with her. Granted, she shouldn't have been driving if she had had a glass of wine; however, it would have been fine except for one bitch in the car that she tapped with hers insisting that they must call the police. They could have just exchanged insurance information. Now, I am not in favor of drinking and driving and know that drunk drivers cause a lot of sorrow and destruction of lives. But when your friend doesn't exercise good judgment and taps -- and the damage was minimal -- another car in changing lanes in rush hour traffic, it just doesn't seem right that she is the one in jail when others who are drunk out of their minds are causing fatalities and getting away with it. I'm just glad no one was hurt and that she is okay. It didn't help my sleep last night though. And I had a card returned via US mail from the youngest daughter marked "no longer at this address". I checked with her neighbors and found that she is still living in the condo. One possibility is that it was misdelivered and someone else marked it that way.....but I am not holding my breath. I will send one more card to see if it is returned. I just don't know what to say to her except that I love her and miss her. Any suggestions? I'm off to read and go to sleep....hopefully.
