Is it normal to be in this mental state?
I've always had bouts of depression and just coped. However, last autumn I lost someone very close to me and it tore me apart.
Recently I've developed these phases where I'll go a few hours to a day uncontrollably laughing and talking really fast and making no sense. Just saying my thoughts out loud and acting really odd, my friends often think I'm drunk or high or something. I instantly set about writing my novels and can work for hours on end without tiring and become convinced I'm a genius or something.
When hyper like that I also set out to do stupid things, with alcohol or sex and what have you.
Then I'll suddenly just be totally crushed and feel worthless and have this kind of pent up feeling and I'll just cry and cry and just want to sleep all the time. This has gone on for months before. I've thought about killing myself many times. If anyone talks to me when I'm like this I'll end up inexplicably screaming at them.
But then I can go for long periods of time feeling relatively balanced. The people around me are pretty much unaware of how I feel sometimes because I can usually try and seem alright.
Is this normal?
