Well, you moved your entire life to a different country (and to OHIO) and you moved in with someone you didn't know very well. I would hesitate to blame hormones entirely.
I went through "my own private summer" at age 45. Thank you baby Jesus for taking away the migraines. If I would have known, I would have had a surgically created "change" when I was thirty. I mean - I knew at 16 I didn't want kids.
