My depressive episodes started in my late 20s. It caught me by complete surprise.
I was a relatively happy teenager (well, as happy as a teenager can be I suppose), and I absolutely loved my early 20s. Aaaah, my early 20s. Young. Healthy. Good friends. Great sex drive. Great sex life. I felt invincible. At the age of 26 I immigrated to London. The adjustment was difficult, but I disregarded and dismissed the ‘negativity’ and carried on regardless.
