I was sixteen. I had been having some health problems and they did all sorts of tests and couldn't find anything wrong. I was at the doctor without my father for once and the doctor brought up setting a psychologist and i burst into tears so he made the referral. I was massively depressed, and my health problems were because I was living on like 800 calories a day but I didn't tell anyone that. Well, after they sent me to a psychiatrist and put me on antidepressants I started eating more normally but... joke was on me... my health problems continued and I eventually developed seizures on top of the depression. Anyway, I had several (about ten) inpatient psychiatric stays as a teenager.

I've been in therapy off and on for decades. It has helped me cope with my major depression or bipolar disorder (depending on who you listen to), and my borderline personality disorder as well. Right now I only go to therapy once a month.
