Reb SITUK, I think you can still consider yourself a tinuk shenishba - your troubles now stem from an problem that started long ago - and unfortunately, because of how twisted the world is, you had no idea that there was anything wrong with getting involved in those things.
Heck, even within certain orthodox communities, watching movies is considered OK, even if they contain all sorts of things we shouldn't be seeing.
So you're starting out fighting against something that you grew up being told (in some way or another) was OK. That's an incredibly difficult fight, and it would be naive to think that it's would be easy! It is truly a war, and a war is fought in terms of a long-term victory, not simply winning one battle (although winning battles is good :D).
You're constantly growing and changing, and reminding yourself of how you WANT to be, can be one of the tools you use to help. No one is perfect, we just have to remember which path we ideally would like to walk on.
