hello I feel my boyfriend may have a mental disorder such as bi-polarism. it seems his mood changes frequently he goes from aggressive, angry, irritable, anxious and nervous. its like he becomes a completely different person. then He will go back to normal. other times he will be over loving and attentive. then back to angry and normal and so on. what could this be???? the oddest thing about this is after his angry episodes its almost like he doesnt understand that it is wrong. like in those moments he cant discern wrong from right. It is hurting our relationship we have a child together and I am trying really hard to find out what could be happening. what is happening?! does this fit any symptoms?? we are going to a dr. next week but i would like an idea of the problem now. also what should be added is before our child as a young teen he did drugs heavily, every drug you could think of besides crack. could this be a reason why? is there anything medication can help? please anyone
