I feel out of it a lot like my head is floating & i always think there is something wrong with me. i think its anxiety. what can i do to alleviate it?

Lots of things: Talk with the doctor treating your ocd about the new symptom. Find a relaxation technique that appeals to you - mindfulness meditation, exercise routines - there are many roads to the destination of stress relief and anxiety control or reduction. Prozac (fluoxetine) may not be the best way to handle your condition, so ask if a change might help. Also, have a doctor look into non-psychological conditions too.
