if you mean not safe as in others can see what you write correct basically when on line consider posting like sending a post card through the mail - nice picture but the letter content can be seen so don't place any information that you would not normally send through a mailed post card of phone number and so on that would disclose your real world identity.

As for the help you recieve here yes it is safe to post your opinions and what help you need and your supporting others.

You will recieve resourses and support here but people here don't perform as professional therapists and psychologists and psychiatrists. its like any real world support group without professionals attending. From time to time Doc John (who is a professional and runs this site with the help of many moderators administrators and behind the scenes professionals) pops in to make sure the site is what it should be and offering his opinions and posts and also by lending his expertise through answering questions during tuesday night chats.
