Just opinions which you can take or leave -
You say "a full detox with paleo". I'd not worry about detox. AFAIK, there are some techniques, near infra-red saunas being the most significant, that actually will help people eliminate heavy metals, etc. that really people's normal systems should be able to cope with but can't. But most of what's offered doesn't help and is a con. Anything like that is probably best put on the back burner and forgotten about for a long time. In comparison with supplying the nutrients your body needs and stopping giving it what it doesn't - feeding overgrown yeasts, for example - it's a distraction. And even if it did work, insofar as it did it would probably make you feel ill if you're not as healthy and robust just through normal diet as you could be.
"Rest and stress". Sure, absolutely. Also add sleep (as much as necessary in a properly darkened room) and caution with exposure to light after the hours of darkness.

Then you probably don't want to force it. You might also have trouble digesting the healthy fats you do need, if you've been avoiding them for years.i don't really have much of an appetite for big hot fatty meals, and i hate cooking.
You could take a little good-quality grass-fed beef and fry it gently in butter (or preferably ghee - clarified butter) leaving it somewhat rare. Then slice it into tiny strips and put it into some nice rich gelatinous broth you've previous heated. It helps digestion of the meat, and broth is very gut-healing.

You don't need to make the broth yourself if you hate cooking. You're in the UK, aren't you? Waitrose do the genuine thing from Heston:

Well, what really would you be missing? Up to you, of course, but if it impedes gut-healing and the absorption of nutrients it's doing you no favours. Real organic yoghurt from milk, dairy product or not, would be better for those aren't actually dairy-intolerant, and probably no worse even for those who are. Real food. That processed soy stuff, all inherent problems with the beans aside, has to go through processing that you just couldn't do without factories and equipment and processes that weren't even round the blink of an eye ago in time. Real yoghurt? Made for centuries with nothing more than milk and a wooden bucket that was well-impregnated with the cultures that ferment it. But maybe you're right to avoid dairy products for the time being. Everyone is different and there's no way of knowing what would suit you.i think i will probably live on egg salads and soy yoghurt with berries and nuts the first while till i have the energy and motivation and appetite to cook proper meals. don't get started on me about soy - you can't take everything away from me!
But you eat fish happily, anyway. Plenty of cold smoked mackerel, tinned sardines and salmon, and others around in the UK that don't require cooking.
You should probably supply your gut with some fermented food. If yoghurt is out - on account you want to eliminate dairy products - then you could eat some fermented vegetables. They can be a little strong-tasting, but you don't need more than a spoonful or two with a meal. If that appeals as a suggestion, look around for real live sauerkraut. (There's fakes stuff, too.) You can get it via Amazon. You can also get a host of fermented vegetable dishes via Red 23 (the kimchi is pretty good):

You'll see Bio-Kult probiotic pills on that same page. Those are a pretty good probiotic and may be worth trying. The GAPs lady, Dr. Campbell-McBride helped to formulate those, I believe. You can also get those via Amazon or direct from Bio-Kult:

I hope none of that comes off badly - I know you didn't want to hear anything against soy - and that it helps.
