Once you are strong enough to help others, you might want to do so. Everyone here is an example of this. By attending a conference which shows the unity of the survivor movement, you are doing this. By being here, you are helping everyone get stronger. A discreet object which you find comforting that might help you stay present may be a good idea to have at the conference.
Some people use teddy bears.
Others might have a blanket, pillow or other item. If an item is comfortable for you and safe for you, that s great. But I believe this can be a good thing, but there are also inherent dangers involved in these items as well. Any item that could trigger a child alter may not be a safe one to have around. So, you may want to discuss this more afterwards with your support person.
