I believe we are here for a reason and that reason may be to continue our personal growth or to help others to complete their grow and path, every time we die we have the option to come back and to continue that path, our suffering is to be able to figure that path out and to keep growing as a whole.
I also believe in a God, a God that gave us the freedom to make our own decisions and to choose our paths by using our own convictions and experiences.
A movie once mentioned something about a perfect world :
"The first Matrix failed because it was too perfect. It was a virtual paradise, a utopia for humanity. Unfortunately, humans are not accustomed to living in a perfect world, and the test subjects rejected the simulation because it just wasn't right." << The Matrix Reloaded >>
For me that quote is perfect to describe why God allows people to be blind, deaf, transgender, etc. Can you imagine us living in a perfect world? We would not have to make any options, it would be horrible, everything would be already done and people would not have anything to look forward to.
When i was a kid I used to go to bed crying and asking God why this happened to me, asking to be a girl when i woke up the next day, I did not understand my feelings and the reason for me to be in a wrong body, but not matter what, every time i made a choice i made it thinking that it would helped me reach my goal not matter what.
I am 37, and I had to go thru several experiences to get where i am, but these past experiences are the ones that helped me understand my path and helped me accomplished my goal, it took me 35 years to understand as well as to get in peace with myself to be able to make the final decision and to reach my goal, but not matter what, I do no regret any single moment for the last 37 years, I would gladly go thru all of it again and as Ms Grace mentioned, these experiences helped me "to learn I didn't have to adhere to social strictures, to learn I was in charge of my own destiny, to have the courage to stand up for myself, to live my life to the fullest without placing blame, without hating myself despite what I perceive as my deformities, to love myself to be grateful for what I do have in life and be grateful that I wasn't born with any of the disabilities I mentioned above." << Quote from Ms Grace from Post #2 >>
The only thing i can say is, be strong, plan your life and have personal goals, try to accomplish each of your goals not matter how long they take, but most important, always be you no matter what, even if you are not able to show your real feminine you for a long time make sure that every decision you make is done thinking that it will reduce the path to get to your main goal.
