Why do Trans people not go for full transition?

For me when I struggled with my identity I truly felt like I was born in the wrong body as the wrong person if I had my way I would've fully transitioned. So why are there so many who dont have that desire? why would someone feel like they are in wrong body but don't want to fully transition. Well one reason is the dangers of the surgeries and also the fact you can't go back is another. So it begs the question why are there so many who allow those reasons to hinder them from going for a full transition to be who they feel they are? There is a deeply physchological phenomenon with this that skews the so called statistics on trans people that mainstream has put out there. We need to be asking the hard questions and digging into this cause messing with bodies and hormones can have detrimental effects and life long consequences as I know with my own life.
