As someone in a rather similar position (my life has been fucked up in so many ways from procrastination), one tip I can give you is to get rid of this mindset.
I feel horrible whenever I waste lots of time, looking back on how I spent my day, thinking "what the hell is wrong with me?" But the thing is, that attitude feeds much of the procrastination. I am an odd mix of being a total perfectionist, and really lazy, so it turns out that whenever I'm faced with a task that I don't really want to do, I'm quite adept at rationalizing ways to avoid doing the task. I think about possible roadblocks, or pretty much anything that would keep me from attaining my sought-ought perfection, and knowing that I'll have the same strong negative reaction later on that I always do, I just won't do it.
If you beat yourself up over procrastination, you're just subconsciously teaching yourself to not even think about whether you're procrastinating or not. Whenever you try and shift from unproductive tasks to work, it's much easier to just stay with the short-term dopamine kick of reading the internet or whatever, rather than dealing with harder decisions about what you need to do in the long term to be happy. Yes, this is backwards. Your subconscious is not very rational...
So, from my point of view, just do everything you can to recondition yourself to not hate working, and to not hate procrastination either. Just try to feel the bit of fulfillment you can get from writing code or whatever, basically just getting your shit done. Have patience with yourself, infinite patience, and know that it takes lots of work to get where you want to be, but it's worth it. You're the only one that can do this.
BTW, if you're like me, a perfectionist to the core, consider that this comes from a deep-seated insecurity, a part of your brain that tells you that you'll never be good enough. At least, that's the way it is for me, and it's been that way since my childhood, as far back as I can remember. On this front, I'd just try to evaluate your emotional well-being in the most balanced and unattached way possible. Get help if you feel like it. As others have mentioned, meditation can be amazingly helpful here, and exercise too. Unfortunately, they're both quite prone to being procrastinated on.
Good luck...
