I think you need a med adjustment, but not necessarily one that is going to put weight on you. Your mood swings are so severe that adding some additional mood stabilizer may level you out some. Sounds like you have a lot going on, and maybe need to cut back on your expectations of yourself for a while, too. Dealing with family is always hard when in a mood swing, esp family that doesn't understand. I think printing out your post and making an appointment with your pdoc asap is a really good idea. You're suffering way too much for your meds to be where they need to be.
I'm glad you've found a place to vent. Another healthy thing is getting it all "off your chest" and this is a good place to do that...
