I never said it was "easy" but if you truly want to quit crossdressing, jou can. It's just a matter of willpower. Many people in this world have quit smoking, alcohol and even drugs. These are much harder to quit because they are physically or chemically addicting. I quit smoking more than forty years ago, without pills , patches, etc. I just said to myself that I wasn't going to buy cigarettes or smoke them any more. I got very sick about six years ago and the doctors insisted that I quit drinking. They said I was an alcoholic and needed to join AA. I gave away all the alcohol in the house to friends and haven't had a drop since except beer and whine that I occasionally cook with (but don't drink). I didn't join AA.
I am no super hero, just a normal person like you and most everyone else. If crossdressing is causing trouble in your life and you think your life would be better if you quit, just do it. When you get up in the morning, put on a pair of briefs instead of panties. Put on an undershirt instead of a bra. Slacks or jeans instead of a dress. You get the picture.
The bottom line is, it's entirely up to you. Quit or don't quit.
