I've been on T 3 years, full-time for 5. In that time, I've been married and divorced, lost 3 jobs due to transition/intolerance toward transfolk, lost a few friends, had my beloved dog stolen, lost my family for a year (and now they're only back to tell me I'm an abomination), haven't been able to get work for months (unknown as to whether or not this is trans-related), suffered severe bursitis and back problems from binding, have been assaulted for being trans, and just recently had my dad threaten me with violence if I insisted upon being treated like a guy. The last on the list caused me to leave my folks' house, which was the only home I had, and I've been living in my truck with my girlfriend for the past week and a half. Every time I apply for a job, I have to show two different IDs--- the state-issued one with the right name and gender marker, and my SS card, with the wrong name. I have to fight ignorant doctors to get T refills, and have been forced to go off T multiple times due to this.
Would I ever go back? Hell no. I have no assurance that anything would have occurred differently had I not transitioned, and I can't imagine I'd even still be alive if I hadn't. But yes, you have to go with what resonates best with you.
