I have extreme mood changes during a day, sometimes it's from extremly happy to totally depressed, in one moment everything's okay, then suddenly I get cravings or think I just want to end up my life. I tried medication, mood stabilizer, but they didn't really help and I had a hard time with side effects. Everything is so extreme. I could Imagine it stressful for my surrounding. That's the only positive thing of not having strong social bonds, I can't negatively affect someone. Often it's stressful and I need to do a lot to prevent a crises. Craving means to fight every single minute, 15 minutes are a long time, half an hour. I had a dream last night about a better half, a someone, a relationship. It was a great dream, sadly I had to wake up. :-/
The only positive thing about mood changes: bad mood don't last long as well. But I also have to fight depression and whenever that comes into play, I try not to forget how to smile.
