Turner Syndrome Support Group
Turner syndrome encompasses a number of chromosomal abnormalities, of which monosomy X, is the most common. It occurs in 1 out of every 2,500 female births. Instead of the normal XX sex chromosomes for a female, only one X chromosome is present and fully functional. In Turner syndrome, female sexual characteristics are present but underdeveloped.

I also didn't find out I had Turner Syndrome until I was 18, please feel free to message me if you'd like to talk! I had a lot of your same thoughts regarding having kids and letting a future partner down
