Have you tried to let them know that you feel this way? Alot of times people are so wrapped up in what is going on with them and their interests that your needs are not acknowledged, not because they dont want to hear but basically because when you are an attentive friend, you make them comfortable with controlling the conversation.
Try getting a word in here and there and keep at it. Maybe then they will see that maybe their are needs and things that you must talk about.
Hope this helps and welcome to our forum!
