If you have a sense that this is an addiction and that it seems confirmed by your therapist then staying away seems best. Posting about it just seems then to feed the addiction because you'll wonder about the responses. If this is a genuine issue then I wouldn't post about it, but just try to refrain from acting on the impulse to post. I've left many a site before when I got too involved. It is a matter of balance and if you are not finding that then the best thing to do is change it and see how you respond to the change and see how long it takes for you to not need it.
