It seems to me I'm the only one in my family who hasn't been diagnosed with anything (lol) .

My mum has recently come off antidepressants after being on them for most of her life, through 2 bad marriages one of which I suspect was abusive although she won't talk about it.
My 21 year old sister is currently depressed after her second ectopic pregnancy in two years, she was also depressed and suicidal as a teenager.
My eldest brother (25) has anger issues, dyslexia and undiagnosed Aspergers and was depressed and suicidal as a teenager and self-harmed until very recently.
My other brother (23) has Bipolar (not sure which type) and struggled with drug addiction throughout his teenage years. Nobody is sure whether the condition or the drugs came first but we believe it was the condition and the drugs were an attempt to self medicate.
Although they are struggling, all of them have support through the family and are coping and improving. I am proud to be the aunt of three beautiful girls and they have shone a wonderful light into the darkening lives of my siblings.
