hey, regarding the stress, and the exhaustion, have you tried running/jogging, or even just a 30 minute walk? I really LOVE doing it early in the morning, the early sun rays and the birds and the clean air really help me relax my mind. it also helps with depression too
if I can give you a hint, any hint! it would be this... try also to see what good is happening when you take porn out of your life. try to imagine what you will be able to do, once you are cured and fixed from this bad habit. how you will be more 'human', sensitive, and life a happier life, and specially, not feeling guilt about yourself anymore.
it's very important, I think, to also concentrate on the goal, the final objective. this way, you feel motivated! you see the light at the end of the tunnel, and you just want to get there as fast as you can.
do not focus ONLY on the triggers and etc, it will only make you see about all the hardships of the process. try to see also what good things are already happening, and try to imagine how the future will be.
anyways, remember we are responsible for making heaven or hell for ourselves, while here on Earth.
life without porn is heaven - natural feelings and emotions towards life and one another
life with porn is hell - all you see is different things that can give you pleasure, no deep, inner, calm joy
u know... today when i was walking out to college (I am starting also, Psychology, 1st period, wasted a lot of time with many things, long story, don't mind sharing some other time) it started raining, and it was very brief, lasted about 5-10 minutes. I stayed under a tree, and waited for it to end, and at that moment I started "watching the time"... because i had nothing else to do, u know. and, i looked at stuff, and instead of worrying about anything that was on my mind, I just... blankly stared at the reality in front of me. I even remember, an old lady drived by and I realised: right now, right this second, we have absolutely nothing to worry about... really, think about it: only things that get us thinking, are made up by our minds. like, "I need to graduate well, so I can have a decent job and not starve", thinking about the future with logic and reason, but right now? You're not hungry now. there's not even anything threatening your satety, as of now. so, if you think about it, we shouldn't be worried at all, ever. u know? just thinking about what needs to be done, and doing that. and while we have nothing to do, thinking about absolutely nothing! ...the problem is, we're very accostumed to overthinking, and preocupating... and it's impossible "not to think"; you have to focus you attention on something else, like, the imediate reality of your surroundings, or something like that. for example, when you see a tree, just see the tree, don't think about the tree, don't think the tree, see the tree. get it? he he . . . anyways, just something I guess I wanted to share... and I hope it can also be useful to "feed" your mind!
good luck, man. live long, and prosper.
