Welcome to the forum.
I think we can all here feel your "discomfort", but hey, we are all in the same boat.
you have done well sharing your story. the next step is to probably discuss your intentions. what do you want to do? is it "I am happy this way" or "I will go as far as it takes to solve this problem".
after that you need to decide how you would like to get to this decision.
I am not sure exactly why wearing the bra, but if you are comfortable with it then carry on.
Your body mass index is very high ie you are over weight. try to lose some weight slowly. this will take you around 1yr.
If your breast enlargement is glandular, then the only solution is surgery. could you take/afford it?
Gynecomastia is a stressful thing to have but it is not the end of the world. I go swimming, I get naked with my girls.....if they dont like it, its their problem but this doesnt mean that I dont try to erase it if this is possible.
Good luck. let us know what happens with you.
