I'm similar to
@TiredBill, except that I am struggling to manage work with social life.
I went from stuck in bed and the house to working a physical job (30hrs, five days a week).
This is within a two-year time-frame.
I don't know when I developed CFS/ME. Sometime six years+ ago. My migraines increased to chronic levels, and I now believe this is because of CFS/ME. I completely misinterpreted my symptoms for migraine or cold/flu-related things.
Funnily enough, seeing the doctor and taking their advice [for stress/depression] led me to my first ever relapse. I had had some hard periods before, but this was a level above the rest.
But it led to the fortune of identifying that I had a chronic illness rather than just stress issues.
A combination of things has helped over time, but pacing was my start from that relapse point.
I had to take it step by step. Doing what Bill said, just doing what I could. I would say I kept falling into flares again and again and again when trying to get better. I also fell into situational depression for the first time, so it was tough.
However!! I did not know I had CFS at this time. I did not have a clue what was happening, nor did my doctor.
But persistence was key. That and learning how not to push too far, yet still challenge myself.
It is possible to get better! My specialist said to look at yearly improvement, which (as a highly impatient person) I find horrifying. However, when I do look back, I am improving each year. So that's good.
You know various tools people with CFS/ME use to help. You have access to information about CFS/ME to identify your symptoms, triggers, and so you can learn about yourself. Therefore, you can implement all of that to progress forward with time.
Once I feel I'm relatively stable, I make a change. I did this with my sleep most recently (goal: zero naps, awake for 16hrs per day). I admit, I thought it was a big mistake once I begun. Two weeks in, I felt like death.
In my experience, I feel worse before I begin to feel better. But I worried about work, as I got slower. Thankfully my workload also lowered, so it didn't make a big effect. I could get away with continuing.
A few months later and my body has adjusted. I don't feel more rested, of course. But my aim is to do the best for my body whilst it goes through this. So at every chance I can, I try to do something to help it be at its best.
Not everything has been available to me, but as I go along.. more opportunities come up and I take them.
Someday, I hope to get to a point where I can socialise and work together without flaring up. So that is what I am actively heading towards now. Not purposefully, I am just trying things out and hoping it leads me there.
Definitely don't allow your current self to limit your imagination of your potential self.
