I don't know If I have any sort of depression, but I know everybody on both sides of my family have some form of this disorder; bi-polar, seasonal affect, etc. Sooo, pretty high risk. But there was no-where else to ask my question, and I felt a lot of my symptoms fit in here.
So I'm an extremely happy person, I'm always the one suggesting to do outrageous things, I run up to complete strangers and ask personal questions, very social, extremely sexual, I blow entires chunks of money on "whimsy" purchases, non-judgemental, over-generous, impulsive, energetic, everybody knows I'm the one to dare to do anything. This is how I feel during the day, around people, or with a light on. Yet at night (though I sleep with a night-light) and with a few day-time exceptions, I get periods of seriously wanting to kill myself, planning suicide or cutting, crying for hours, feeling like I've "fallen" into a mental black-hole and just writhing in mind-anguish for extended periods of time, complete/debilitating loss of sexual drive during masturbation or sex, or extreme feelings of rejection or sadness after having sex or getting off the phone with somebody. I genrally have to take medicine to go to sleep just to rid myself of the pain.
Sometimes periods of elation strike me at night and i won't go to sleep until 11am, i just stay up all night on the computer or playing videogames. Sometimes periods of depression strike me during the day and i just uncontrollably cry while feeling nauseus, I just feel detached and empty and put on sunglasses and music. I'm very logical and I usually "think" myself through them, or rationalize why I can't have outbursts of the magnitude I really want to (throwing things, yelling, etc).
I'm confused at what I'm experiencing, I believe I'm a happy person and there's no reason to get serious attention for this, yet I have had 8 sucicide attempts, 3 of which I was hospitalized for. (Those failed attempts just make me sadder when I do feel down.) What exactly can my symptoms be described as? Is there any safe way to reduce the weird sad cycles? I classify myself as a happy person so I really do not understand why usually in the dark, alone, I turn into a completely different person, and sometimes I don't.
