It's hard to know what is happening for you, because there are several possibilities from what you are describing. You could be having a reaction to your med changes, or you could be experiencing a mixed mood state or anxiety, you might be going through a period of stress which is causing the emotions and behaviors, like an adjustment reaction for example, or it could be something totally else, like physical health causes. If you haven't been diagnosed bipolar yet it's a good idea to meet with a pdoc or other professional to try to sort out what is happening. Whatever the case, I hope you feel better soon.
