'I'm tired of doing my hair and make-up': Pensioner, 75, who became a woman in sex change operation 23 years ago wants to be a man again
Now she wants to warn others considering the operation and extend a desperate apology to her family who have disowned her.
Gary says: 'Having a sex change was the biggest mistake of my life. It has left me isolated from my children and feeling like a social misfit. I would do anything to see them again.
'I'm lonely because I want a relationship with a woman but I can't have a physical relationship because I've got no equipment.
'I want to advise others to think twice, it's one heck of a mistake to make and as I have found out there is no going back.'
Gary's horror story began when she sought help for depression from her GP after being made redundant.
During the meeting she admitted to dressing in her wife's clothes for a secret thrill. She says she now realizes this was as far as she ever wanted to go.
But she claims her GP concluded she could have been depressed because she wanted to be a woman and advised her to start taking hormone pills.
'It was all so fussy and time consuming. It was then it hit me, I hadn't wanted to be a woman - I just liked dressing up as one from time to time for a thrill and it should never have gone any further.
'It was devastating. I was a man trapped in a woman's body and I was stuck with it. It was too late to do anything about it. I couldn't believe I had gone so far.
The pensioner is warning others about the procedure after his experience
In 1990 one year after the operation she wrote to her psychiatrist for help saying the operation had been a mistake and asked if she could have it reversed.
'He replied to say I needed to get on with it and embrace life as woman and make a success of it.
'What choice did I have?'
In the years that followed she took up modelling and dance classes, but no matter what she did Gary never felt like a woman.
'I passed well as a woman and those who knew said they all thought I had been born that way.
'But I always felt it was an act. I was pretending waiting for it to feel 'right' but it never did.
Eventually after 23 miserable years she had had enough of living a lie and took all of her women's clothes to the charity shop.
Last year she stopped taking pills to let her facial hair grow back and started dressing as Gary again.
