Ok. Well, I did read your other post. That is where the "everyone is selfish" statement comes from. I'd like to think I'm not selfish, but the reason I said "I'm one of them", is that it is a part of being human. We all HAVE to be selfish, if we constantly gave and gave of ourselves (which I think in the past I had a habit of, thinking that my giving to someone else actually made a difference, and tried not to expect anything in return), made ME bitter. If a mother doesn't care for her own needs, it doesn't help her children does it. It's like the old saying "if the plane is going down, who's oxygen mask do you put on, your own(the moms), or your childrens?" We have to put our own on in order to be alive long enough to help our kid.
So your questions,
No, you're not limited to how many or how often you post on any of this forum or subforums. There does seem to be a limit to how long a post is, but honestly I once recall seeing someone post at least 10 times the length of your other recent post in the depression forum. So, you can refer to the Community help and feedback sub-forum for any questions I can't answer.

I'm not here for any selfish reasons or a thanks from you. I would truly like to help you get out of the hell you feel you are in.

I don't know of any forums myself, that are out there with real psychologists or proffesionals, this site is strictly just regular people helping people.

Generalized questions can be asked in the "Questions and Answers" sub forum. I think it's called that. I'm tired this morning and that is as much as I can help right now. I again ask you to please go ahead and try to relate what your looking for answers for. You are anonymous here, and people can be kind here. I've had plenty of help here from nice members.
