Odds are very high if you continue living your life unhappy and to please someone else that you will become one of the 41%. The only reason I didn't was a friend caught me before I was able to execute my plans to kill myself.
Some people are unhappy because of circumstances they cannot change but let me ask a question - What would you think of the ethics and morality of someone you knew who was deliberately living a lie? Would you trust that person? Would you have a high regard for that person?
Living a lie for someone else's sake is corrosive. You know the lie is there. You know you are lying to everyone you claim to love. Little by little, you self-esteem dies, because honestly, how can you respect someone you know is deliberately living a lie? You withdraw and your rare social outward moments are you lashing out in anger, not because you're really angry at whomever, just because that latent anger inside at your own known lies and they become a convenient target.
I was known for a legendary temper since I was young. No one knew why. It took every fiber of my being to avoid lashing out physically at someone, and who knows? Maybe I eventually would have failed at that and hit someone I loved. I came to hate myself, to despise my body. Intimacy in my marriage suffered off and on for years and years.
My spouse knew something was wrong. She later told me she wondered if I was gay. If only it had been that simple, hm? But she was afraid to open that can of worms both because of my temper and because she feared the answer. And when the answer finally came spilling out years later, she accused me of lying to her and deceiving her throughout our entire marriage.
So what had I gained by living my life for someone else? Years of unhappiness. And my marriage is over anyway. And two of my three adult children refuse to speak to me or allow me to see my grandchildren by them. What did my sacrifice gain?
Absolutely nothing. Nothing I did was appreciated even one iota by those for whom I did it. I was a fraud and that's all they chose to see.
So I'm going to close here by saying that years from now, you're going to be in the same boat as me. You will reach the end of that rope. You will either try to kill yourself or be forced to face yourself. And if you face yourself, odds are high you're going to lose everything you love as they come to see your entire life as a lie, a fraud, and a deliberate deception of them, nevermind what you supposedly did for them.
Knowing what I know today, if I had the chance to do it over, I'd have said to hell with it all and just gone and transitioned years ago. Living my life for those I loved turned out to be one of the sharpest, most painful daggers I had to face when I discovered that their love for me was completely conditional, very limited, and easily thrown away at the slightest excuse.
I hope and pray that you do not end up where I ended up.
P.S. Consider this...
Selfishness is not living as one wishes to live, it is asking others to live as one wishes to live. And unselfishness is letting other people's lives alone, not interfering with them. Selfishness always aims at creating around it an absolute uniformity of type. Unselfishness recognises infinite variety of type as a delightful thing, accepts it, acquiesces in it, enjoys it. It is not selfish to think for oneself. A man who does not think for himself does not think at all. It is grossly selfish to require of one's neighbour that he should think in the same way, and hold the same opinions. Why should he? If he can think, he will probably think differently. If he cannot think, it is monstrous to require thought of any kind from him. A red rose is not selfish because it wants to be a red rose. It would be horribly selfish if it wanted all the other flowers in the garden to be both red and roses."
