Good for you trying to kick porn addiction!
Are you ashamed of your crossdressing, or does it negatively affect your life? I have found, like many others, that the consequences of completely abandoning that part of you are more destructive than allowing some crossdressing in your life. Reboot and purge as you might, it doesn't go away, and you may become angry and unpleasant from the repression.
Of course, you can become addicted to all kinds of ordinary activities, like sports, work, or restoring vintage cars, and no-one thinks any less of you - unless they get in the way of your relationships or responsibilities. Maybe consider crossdressing as an ordinary and fun activity that you just need to balance with the rest of your life. Good luck!
