weird mood swings

I've recently been diagnosed with depressed and perscribed 75mg of wellbutrin. I undestand that it takes a few weeks to take affect, but after two days on it, I noticed an automatic change in my mood; thoughts were racing through my head like three people talking at the same time, which makes it hard for me to not stutter a bit when i talk. I have this urge to scream and laugh manicaly--which i given into just moments ago. Luckly no one was home. And i threw a steak knife at the kitchen wall, because i thought i could be likea ninja with ninja stars. I really don't know if it's the medication, because i just started two days ago... God i know this sounds crazy, but it happend. Actually things like this happend to me thoughout my life; I get serverly depressed to the point of thinking about suicide for couple of weeks, and suddenly have this bubbly engery to do things and act super hyperactive and outgoing. It's like when i'm depressed, i see myself as a fat *** pig, but when my mood changes, i see myself a beauiful and outgoing girl. I think my mother is really fed up with my constant mood changes and quick change of intrest that she can't keep up with. Ugh, i don't know if it's normal or not. What do you guys think?

It sounds troubling, definitely. Talk to your prescribing doctor, see what they say?
