You have good insight. You know that right now you are not yourself. You're on the verge of breaking out in public and you're finding it difficult to keep your impulses at bay.

It's time to make contact with your pdoc. As has already been mentioned, not all medications come with the side effect of weight gain. There is something out there that can stabilize your mood but you need to work together with your pdoc to find out what it is.

Be well.
