Hi Losschasing,
If you are unsure as to whether or not you have an addiction then take a look at the 20 questions they ahve on the GA site.

They are as good an indicator as I know and are relevant whether or not you ever decided to go to a meeting.
Read the other stories here. You will see a lot that you will relate to. You will also see the success stories – what are they doing that you can apply to your own situation?
Keep posting, you can stop gambling.
