When I think objectively this seems so trivial.
Well, shoot, Lorraine - there you go, invalidating your emotional pain and needs. You're judging yourself, and putting more pressure on yourself to behave a certain way, instead of saying "Fuck, this really hurts and I deserve better!"
I'm going to go back to primitive brain theory now, so please bear with me.
As biological beings, our
only job is to survive just long enough to breed and raise the next generation. That's it. That is the only job of all living things. Think about that in the context of the primitive world, and compare it to our current world and the way that most of us are privileged to live safely with our first-world problems. SO MANY first-world problems, pressures, emotional threats, and existential worries... it's never-ending these days.
Eons ago in the primitive wilderness, the development of the human brain was a complete anomaly in the animal kingdom. I can assure you that it was not definitely NOT designed to comprehend the complex stressors of our modern world, stressors which only developed within a tiny sliver of time on the massive timeline of human evolution. If you define "modern" as starting when humans began to congregate in large communities, stopped knowing all of the people in their community, and were forced to develop complex rules in order to continue surviving, it's a teensy amount of time - our brains need a lot more than a few thousand years to significantly evolve over the entire human species. And look at the changes since the Industrial Revolution in less than a few centuries, the massive changes just in the last thirty years, and the dysfunction following on those changes in the last 15 years. No wonder we're suffering from an epidemic of fear and pain.
To circle back to your current suffering, it's important to understand that different animals evolved varying types of relationships and/or societies for one reason only - to ensure their survival. Our human evolution centered around small communities of individuals who spent lifetimes together or very close by. Unfortunately, the modern world along with overpopulation has brought Separation, Isolation, and Abandonment, which are
powerful stressors on our emotional well-being, because in primitive societies, those things resulted in non-survival, aka death.
Separation, Isolation, and Abandonment: this is what you're dealing with. It's normal and it's natural and mental health demands acknowledging, facing, and accepting that these exist and they are what is hurting you.
What is unnatural is the amount of separation and isolation we experience in today's world. It is not serving our emotional stability and well-being in any way, shape or form.
Give yourself a break, and also take
@BloodMoon's advice to be proactive and ask for what you need. No self-judgment, no self-pressure.
