Yes KingDavos I have been having therapy once a week for just over 4 years and this has helped me identify and then dismantle the false self. (I actually had therapy twice before in my earlier life but it wasn't right or the right time - one therapist reminded me of my mother! 
).
With the false self I built mine up unknowingly from babyhood as I quickly learnt that showing emotion of any kind was frowned upon by both my parents. It probably started in the womb. It wouldn't surprise me if my mother left me to cry in my crib, although I have no way of knowing. She did tell me once that she used to leave me outside in the garden in the pram all day so she could get on with housework, and I was certainly never ever held or comforted.
Anyway, crying, feeling sad, hilarity, fear - all of these emotions were mocked, shamed, or scolded and I developed a neutral facial expression and monotone voice to hide my true feelings. I learned to be incredibly forcefully independent to the detriment of myself as asking for help was also a no-no as it would have shown weakness. And I learnt that if I do it all myself the only person I am relying on is me so there's less chance of being hurt and feeling that pain.
In adult life for my teens, 20's and 30's I went through life wearing my false self although it had been created as a survival mechanism for my family home and no longer served me in the wider world. This resulted in people pleasing at work and in personal life, saying yes when I felt no, laughing at jokes I didn't find funny, saying I was ok when I wasn't, taking part in things I didn't like and fear of confrontation - basically no sense of my true self and no boundaries. Never ever listening to or even hearing my own needs. Cue a whole bunch of abusive relationships and people taking advantage of me.
It all came to a head aged about 34 when I had some sort of crisis. I lived alone and I remember wandering outside in a blur and it's hard to explain but I just felt dead. I just sat there and cried and sobbed for days and thought about checking myself into a hospital as I believed I was going to die, I didn't know what was wrong.
Thankfully I fought to find a therapist on the NHS (finances wouldn't stretch at the time and my local borough said there were no places). I had to argue my case and jump through various hoops. This sheer instinctive fight in me told me that deep down there was something in there - a life source trying to get out. I wasn't dead. The therapist helped me work out all of the above and after about a year of simply crying throughout every session I slowly started to feel better. She helped me practice gradually being my authentic / real self by saying no to stuff, or risking others' disapproval by saying or showing what I really felt, positive or negative. I started to "nourish" the little burning kernal inside me that was my true self so that it slowly grew and started to squeeze out the false self.
Eventually I met a guy and from our very first date I promised myself I would be 100% real - no people pleasing. In the past I would have agreed I liked Star Wars or something, just to look attractive, but this time I was the real honest and open me. I didn't know where it would go and I treated bit as a sort of experiment, tentatively taking it step by step to see if I could start a new relationship on this new healthy basis - and was very honest with him about it all. And the best thing is, 3 years later we are still together and he loves me for the real me. We are getting married too. :-) I never thought this would happen to me and I think on some level my whole life I believed I didn't deserve "normal" happiness (marriage, home, kids etc) and guess who's voice that really was??!
Anyway, I didn't mean this post to be so long. But I tell you all this in case it helps as I wish I'd known half this stuff sooner. The knowledge didn't cut out the hard work, but it can be a lightbulb moment that helps you to seek the help you need. I felt like I had been living behind a pane of frosted glass my whole life, and at the age of 35 that glass was finally lifted away. I may have left it too late to have children of my own - only time will tell, but I am convinced I'd make a bloody brilliant Mum (which for years I feared would be the reverse). I am now living my life the way I want to and reclaiming my life. As a result I feel more like I'm 25 as I missed out on so much of the "normal" stuff.
As I said above, my actual interactions with my NM are still triggering, and recently with my wedding she has a sudden excuse to try and take control again. So its constant daily work to try and get to a better place like 3ChangingforNow who seems to have made incredible progress.
