I know what you mean about the depression. If I may...
I have a bad habit of getting myself off in bed in the mornings. It gives me the rush that we all know so well which gets me out of bed...eventually.
I know in advance that when my girlfriend arrives she will not accept this behavior. Why would she? It is gross, selfish, immature, childish.
Sex in the morning. Completely different. That is something shared, and if done right, mutually beneficial. But masturbating in bed is abhorrent.
So, what do I do. I throw myself out of bed as soon as the alarm goes off. (I also have an alarm in the office down the hall to get me out of bed). And I don't get back in bed.
When I live with Jenn (my girlfriend), she might find this habit peculiar, or even weird, but it is much better than playing with myself beside her like a 12 year old.
Do you kind of get my point?
The depression is
1. Partly withdrawal
2. Partly a void in your life.
The withdrawal is quite literally your brain wanting its fix. Like the other posters have mentioned you can do exercise to battle the withdrawal, you can eat healthy, whatever works. But it is something that only time will change.
The void in your life is a more pressing issue. It is something that will not go away on its own, the way that withdrawal symptoms will.
You had hobbies and activities you did for fun, like we all did. As your addiction became worse and worse you spent less and less time on these stimulating, reinvigorating activities. Your brain atrophies over time, as do your social skills, etc, etc.
You have to fill that void purposefully, actively. Take out a pencil and paper and write down what you did for fun, what your hobbies were, even what your interests are.
Interests...remember those?
Porn makes us rediculously boring and one-dimensional. How? By erasing our passions, our interests, our active selves, the core of who we are.
That is why we become socially inept. Not because we are not capable of being social, but because we can't relate to ourselves, let alone other people!!!
These are things you (and I) need to do simultaneously. Commit yourself to dusting off that camera and taking some photos. Or doing whatever makes you you. You will probably be out of practice and suck. That happens when you stop doing something. Be patient and get back into it.
And go out there and talk to people. Put the focus on them, and when people do ask about you, now you have the ability to talk about yourself in present tense!!!
Instead of avoiding the topic of who you are and what you do for fun, you finally have an answer. "I am Richard, and I like photography. You can check out my photos on flickr if you want!" You have something to contribute, something to talk about!
Something for us all to work on (especially me)!!!
Best!
