It is possible to be addicted to anything, you can only imagine the strange habits some people have, if it is not hindering or harming yourself or any one in your life than i don't tend to worry bout it too much, but if it is stopping you from growth, if your thoughts about it are consuming your life every second of everyday, if you feel like something might be wrong but your just not sure, but you know something doesn't feel right and this just isn't you. than it's something you should look into finding some tools to help you change.

i'm glad you have taken a step to reach out, personally i do not have this issue, but my best friend does, she knows she has this problem and we actually talk about it and are finding out why she craves attention more so at times than others (and usually it's more) , the more you talk about it all the pieces will start falling into place and you might begin to understand why you are this way.
There is no easy fix and no time frame in which you think you should get better.
