As LDS pointed out, I didn't answer the question so I will try to answer it here. I would say the forum, while not something I am emotionally dependent on, does fill a gap. It does fill the need for human interaction and discussion that I cant get else where. I don't know if that makes me emotionally dependant because I wouldn't die if the sight went down. So no, its an important part of my life, but I am not emotionally dependant on the forum.
I voted for "Help me to understand myself". I don't believe this means that I am emotionally dependent on the site, but I do come here to read and post, and from these actions I do learn a lot more about myself because I can express myself without restraints. I know others have joked about me using the forum as my own little world where no one else I know can enter, and to some extent this is true, but it gives me a greater flexibility in expressing opinions that I may not share in real life with others. If the site were to go away tomorrow, I would be very sad as I have an online family here, and I've learned a lot from discussions here. However, I would not become emotionally unstable because of it.
Since my trip to Argentina I have found even more solace here, yes, that sounds weird, but it is more about keeping myself busy when I have nothing to be busy about. The reason for this is because I feel like I am being uplifted, edified or enriched mentally by interacting with my online friends.
