Fireroses, the best advice you're likely to get is from Becky, here. Somebody over the internet can say anything you want to hear. I happen to be a very accomplished writer and can make someone feel whatever I want through subtle manipulations and word choice. The written word is good at that.
But it's the spoken word that counts. The look in the eye of the person you're confiding in and looking to for help. Whatever your problem, the nicest person on this planet saying all the right things still won't mean shit in the long run. You need to talk it over with someone who can see you, then YOU need to take action. If you're feeling bad, you won't stop feeling bad until you make a conscious decision to do so. I could say all the right things to make you smile or even laugh if you're in a deep depression. I have a talent for that. But when I close the IM window, or navigate away from 8wr, or in an extreme case hang up the phone, you're still alone. I keep saying "I," but this really applies to anyone online.
I'm sure the people you listed are great people (and in one case know so), but ultimately it's you making changes and coming to terms. But a person who is in close physical proximity to you is going to be much more helpful.
Oh. And I'm not a nice person. Just to save you some trouble if that thought pops into your head. ;)
EDIT: Just realized I may not have been clear enough: nothing anyone can say on these forums will help in something like this. Same concept as getting into a cold-ass lake or pool: jump right the fuck in.
