good to see you trying to be proactive when dealing with addiction to cyber sex.
It is not good that your family is away if that means a lot of free time and boredom for you if you have such problems.
Sometimes I can feel building pressure in me that could lead me to unhealthy coping mechanism (I have had occasionally problems with porn and masturbation) so it is possible to avoid falling to it but there is time when some action has to be taken.
I know that many times I have to keep myself busy, in company of friends, to do some exercise and similar and to distract my negative thoughts.
If I'd wait for too long it is not possible to overcome challenge if compulsion already shown.
Please try to be extremely sensitive when talking about your "problem" with people who have same issues. Sometimes it is not possible to hold on and plain talk can trigger some challenges in group dynamics that are anything but healthy.
There is no much that can be said how to deal with some addiction and compulsion. If it is severe I guess therapy is needed to address all underlying issues that are root of compulsion, and I would recommend you to look for professional help.
We can discuss and exchange our experiences but that is not therapy; we are all much different and there are no easy solutions for long lasting problems.
they say "fail to plan, plan to fail".
I love that Tut!
