Depressed since I was roughly 6 (~1992). Diagnosed at 16 (Jan. 2002) by a GP. Not treated adequately until Jan of 2006, when I was 20. Depression manifests in atypical, chronic, recurrent, severe episodes. Dysthymia when I'm not having a major depressive episode.
Generalized Anxiety since high school (~2000).
PTSD from house fire when I was 18 (Feb 2004). Resolved after roughly six years. Panic attacks and social anxiety followed after that, unresolved.
ADHD not "officially" diagnosed because the symptoms are hard to tell apart from depression, but my psychiatrist believes I probably have it.
Borderline Personality Disorder is undiagnosed due to me not having enough traits. However, 4/9 is enough for me to put it here. (Avoiding abandonment, unstable [romantic] relationships, impulsivity, affective instability.)
Idiopathic Hypersomnia remains undiagnosed. I sleep roughly 12-18 hours a day; I do not have cataplexy, hallucinations, or sleep paralysis. I do have excessive daytime sleepiness and all the other symptoms of hypersomnia... HOWEVER no one will probably ever diagnose me with this because of my depression history.
