It may be your medication. I feel this way too. Sometimes I think that people with bipolar disorder feel things more than other people and this is why we are rejected by society and put on medication because of our emotions. Emotions are deep like waves and feelings are just an outside projection. I think we have deeper emotions and when we get on the medication we suffer a loss almost like grief to those emotions even though to me it's kind of a relief... I miss my true bipolar self unmedicated. even though I know it's a dangerous place to be.
