Anyone else think they've suffered from mental illness since childhood? I was talking to my mum the other day and looking back at my childhood we think I started suffering from panic attacks around the age of 5, I can also remember feeling very depressed from about the age of 10 onwards. I'm now 27 and still have problems with anxiety/panic and depression. I have 2 younger sisters and neither of them have this problem, just really hope ds (2) doesn't go through this.
