Beautiful "Friends" star Jennifer Aniston is doing "serious therapy sessions" to get rid of Brad obsession and to accept she has a part of blame for their broken marriage.

The actress confessed she was "shocked and angry" when she first saw the pictures with Brad Pitt, Angelina Jolie and her adopted son Maddox together, because she realized they were having an affair during her marriage with Pitt.

Aniston also declared she already feels a little better after the therapy and realized she has to take responsibility of her actions and decisions for the period she was married with Brad Pitt.

She says, "I've worked with this therapist for a long time, and her focus is that you get one day of being a victim - and that's it.

"Relationships are two people - everyone is accountable."
