I just read a small part of your about me. Moms - stop worrying if possible. My mom, who passed away, was from a different generation of people. To even admit to outsiders, like us, you are BP would be a mistake. Now I must I do not tell others, just people here. Anyway my mom was a difficult person to live and deal with. After I found out so late in life I am BP, I'm very confidence my mom had something as well. After all she could make big swings in her emotions.
Smoking - you have done so well so please do not screw it up and get back on that terrible wagon. I think the Welbutrin (spelling?) truly helped me. It just is not good for you, it's cost way too much, and I truly wish I had given it up sooner. I'm good now. I no longer smoke, drink, or certainly no drugs. My understanding is that messes up your medication and my life has been much better due to the medications. Treat your special, because you are.
Lastly talk to your doctor about your wonderful children who you love so much. Don't be like I was and wish you had been a kinder parent. My brain stole too much from me, my marriage, and my only daughter who is now in college. Don't beat yourself up, just try, and seek out those who can help you.
