I wish you didn't feel like this. Being helpful here is the name of the game, and I think it's great you were trying to be helpful! If you have something to offer on other forums, it doesn't matter if you HAVE that illness/diagnosis. Perhaps you know someone who does, or have some special knowledge about it.
Please keep trying to help. If someone said something about your going to other forums,, THEY are in the wrong, NOT YOU!!!
Thank you for being so helpful. God bless and take care. Hugs, Lee
