Yes - yes to the 'comfortable because I'm used to it' aspect, yes to the 'deep thought' aspect, and yes to the fact that it makes me a better and more enriched person. I enjoy all of these, despite the fact that it's also painful. I think I must be a naturally melancholy person because I've been this way all my life. However I've had a couple months of relative respite here and there, and the person I became bothered me. I lost a lot of depth and substance and ceased to be me. Now I try to walk the line.

For me it's not just deep thoughts but a spiritual nature which is often enhanced by extreme feeling. There's a beauty to the depths I sink to and I become more open to thoughts and feelings I can barely describe... and would likely send others running. However, I've followed this to it's extreme and found myself euphorically suicidal, so I can't go too far over to the other side either.

Or perhaps I just inherited a touch of my great grandmother's psychotic depression. Probably a bit of both.
