My boyfriend suffers from depression but he is often also very upset and agitated, exhibiting frustration by throwing things or by flinging himself on the bed and sobbing. His doctor prescribed him wellbutrin and she upped his dose to 450 a week ago. He's been irritable, agitated, not slept and become hostile and aggressive and almost paranoid. Friday he spent $1250 on something he didn't need, without even researching the thing he bought. This behavior is totally unprecedented and really uncharacteristic. He's often distressed and overwhelmed but it's not like him at all to be paranoid or aggressive. He's never, ever been manic. And he's a careful shopper, to put it mildly. He's 32. I'm scared for him and I'm not sure what to do.
