To stop worrying about every little detail: Prioritize, in your mind, the details that are truly important in the grand scheme. Disregard the other details.

Sluggish bowels: Wow, thanks for being so honest! Laxatives, physical exercise and dousing food in olive oil should do the trick.

Good belly laughs do wonders! Find someone you can just joke with, and tell each other jokes until the tears are running down your face from laughing so hard!! Believe me, it works!! Your stress level will go down... then get in the habit of taking a brisk walk every day, and any other exercise you can think of that is fun... change it up to keep it fun... just HAVE FUN!! :) When you get back, you will forget what you were fretting about. :)

warm milk or just milk

Every morning, I have a large bowl of oatmeal with ground flax seed, chased by fish oil and a handful of prunes (well, you did ask about being costive, right? LoL) And green tea.

Every night, I go for a very long walk lasting anywhere from half an hour (depending on humidity & heat level) to 2 hours.

Drink lots of water. Avoid sugar drinks.

and this is decreases my anxiety and keeps me pretty regular. Just sayin'...

I struggle with this. Haven't been able to find a mental laxative that works for me. I think for me it is the way I consume food. I'm quite a binger. it messed up my gallbladder so much that I had to have it out. I really need to see a nutritionalist, probably more than I need to see a psychologist. Will get back to you if I ever find that mental laxative.

Can recommend Forever Living Aloe Vera Gel, 1 litre.

I used it for the first time 2 years ago and now buy 1 x bottle per month. It improves everything, mainly my bowels but also my skin and complexition.

I don't work for them, but honestly try it. I think the Company is American.

Or check at your local discount healthfood store if you have one nearby, we do here and they have an aloe vera drink I love... it has other herbs with it and is rich in some micronutrients... I use it every day and you drink very little of it along with some regular aloe vera drink and it serves as a whole body detox as well as help keeping one regular. Just want to open you to the idea of looking for something in your local area that works and you don't need to go online or become "glued" to one particular brand, just make sure it is completely organic.
I also agree push the fiber along with plenty of orange juice, in the morning is the best time to do that, along with good exercise and plenty of good belly laughs should start to make you feel better all over my friend. ((Hugs)) Keep us posted on your progress okay?
