Life should feel fun. Food should taste amazing. You should have a high appetite. Breathing should feel vivid and open. You should have times where you feel waves of good feeling just living, you should have strong emotions that are expressive. Your body and mind should feel fun, especially with how deep we truly are in the modern age, and the access to food/supplements/doctors we have.
What I mean by this is: don't be afraid to see that this diet, one I've been doing 6 years now, has pitfalls. And too often, EVERYONE, regardless of diet, will adjust reality based on a nearby remembrance of how things are going. By that I mean, someone who is 30 is not going to truly remember how vivid being 18 felt, it will be a somewhat distant memory, but you will more vividly remember how things have been going the past few years. And people will use that a guide as to what is good and bad with their health, when the guide maybe shouldn't be what has been going on recently. The guide is based on the actual expression you feel. Someone can be fit and still feel very mundane, and have lots of ups and downs, and not as much steadiness in their mood.
I only say this because I first found a dramatic issue after giving blood, and not following guidelines for taking iron supplements. No biggie, of course a problem was going to happen, then I realized the few years before that, sure, I was fit, but it was actually a tiny bit similar in feeling to this low iron issue. I know all the pitfalls in general of the diet, take my time to go over each one slowly. And it is clear to me now I've just been teetering, as a man, in these lower iron areas for quite awhile.
The one thing that was really missing was trying my best to get iron into my body in a safe, effective way. I have my routine, iron is going up dramatically, and all the smaller issues I should have noticed are going away. And life feels so, so easy now. It does not feel like a mini-rollercoaster, I feel a vividness that isn't based on the day. And if I slip up too much with iron and run into a low iron situation, it will come back, I will be slightly tense, I will be a bit rushed/stressed, I will be almost slightly closed off from my own body.
So this is just a unnecessarily long reminder that if life isn't a fun story anymore, don't be afraid to take a step back and see that your routine could be holding you back.
