I would really recommend Transactional Analysis - I study it myself and it is the only thing which got me through PND with my first.
Compared to other therapies TA is understandable to everyone, therapist and the client work together as partners and it is suitable for just one session or many sessions commitment either.
The main idea is that everybody has a "learned script" which we wrote ourselves depending on our childhood circumstances.
Transactional Analysis was founded by Eric Berne, who sought to demystify psychotherapy and developed concepts, language and methods which were understandable to everyone.
Transactional Analysis is a tool which you will be able to use yourself in order to live the life you choose.
To make things easier, here are a few examples of my work with clients(of course all names are fictional):
My first client, Laura, was a mother of 2, 5 year old and 1 year old twins. A successful business woman in the past, Laura was getting depressed staying at home with small children and relying on her husband to earn a living. Her husband was very supportive of her going back into business again, but she was torn between the desire to be a "perfect mother" and re-claim her "former life". In a course of several sessions we explored Laura's feelings about working and her feelings about being a mother, which revealed complicated relationship between her "inner child" and "inner parent". What we achieved was Laura's new ability to rid herself of adopted feelings and prejudices, which did not belong to her, and discover the feelings and desires of her own. With that new skill acquired Laura was able to build a new life, which included her children and her work, the way she wanted it, not the way she was "meant" to live.
Another client, Anna, realised over the course of our sessions, that she could no longer live her life trying to keep her mother happy. The way she did it was by being unsuccessful and not allowing herself to write, which was her secret ambition. Ignoring her mother's statement that "girls should get married" and that "writing is not a proper job", she went on to show one of her scripts to a famous film director. The movie came out this year and was a success. Now Anna is working on a novel.
A couple, Lisa and John, came to the clinic because they started talking about divorce, but were not happy about it. After several sessions they discovered the sticking point in their relationship: their attitude to "family time together". John really loved and valued the time when they all sat at the table, ate and discussed the happenings of the day. Lisa absolutely hated it and stood up and walked out the moment she could. We discussed the attitudes to "family time" that were accepted in Lisa and John's families of origin and how they felt about it. We talked about what this time meant for both of them and how they could arrange it to meet each other's needs. But the main achievement was that Lisa and John were discussing their problem together and finding ways to solve it, rather than bursting into argument or sulking, like before.
