I would echo the same advice already mentioned in this thread, that it is a very personal and difficult choice that should be taken with patience and self awareness.
But there is one thing that hasn't been mentioned, we often like to compare ourselves to people in similar situations to find some kind of familiarity on our outlook but this isn't a fair or accurate representation of our own situation or theirs.
I've read/heard about many trans horror stories, but also found many positive and uplifting stories. Stories of regret and dissatisfaction and stories of great struggle and difficulty that leads to eventual happiness and success. Just like any other kind of people, there are many life stories.
I'm in the exact same position as you, I've started therapy and have been considering transition for a while now. I'm still young (24) without any serious previous commitments and great job prospects in a country with good anti-discrimination laws, I have few friends and none I'm really close to, I've never been close to family except for my immediate family, so my situation doesn't really compare I imagine.
But I'm still having doubts, sometimes I am talking to my friend, or playing games, or studying, or something to distract me from my ruminations. And then I have a flash of thought, do I really want to transition? My life isn't so bad after all (if I keep myself permanently distracted). Then I think to myself, do I need to be suicidal to transition? Can't I just want to be happier and feel more like myself? Should I just put up with it and focus on just getting by as a male, however fake and shallow it gets.
Sometimes I wish it was black and white, that it was a matter of life and death. And some people think that it has to be but I've come to the conclusion that isn't a matter of life and death, for me but a step of self affirmation. I've always been proactive and optimistic and so far with no regrets, why shouldn't I apply that to my choice of transition? Finally feel whole and not fake, finally connect with people emotionally and make real friends, have real intimacy in a sexual relationship, etc. One day it might become really unbearable, should I wait for that?
These are all very personal questions that should be discussed with a professional. And ultimately, only you can really answer them.
I hope you find yourself, best of luck!
