early warning signs panic

I should have seen it coming, I am not my own best friend, I knew but ignored the signs and now I am at a point where I can ignore the signs and die earlier than i really want to or do something about it. People told me in my 20s and 30s to do something because it would be easier then but I let myself make excuses and I kept on eating all the wrong things and too much of the right things and not enough water and way too little exercise. I perpetuated my self loathing and I ate to comfort myself. Here I am looking at the results of my blood tests; Cholesterol, high triglycerides, an inflamed liver, high blood sugar. My legs are swollen with excess fluid and I can barely climb a short flight of stairs. Where did the healthy teenager of so long ago disappear? Where was the turning point, the change? It was everywhere in silent insidious patterns and now here I am decades later wishing I had cared about myself back then. Wishing I had kept climbing mountains, trekking through the bush, clacking hockey sticks and throwing balls through nets and hoops, swimming in icy rivers and cycling the mountian trails but I stopped, just stopped.
The excuses come so easily, I am a young parent and haven't the time, I am working and too exhausted when i get home, I am volunteering and I haven't the time, my partner/husband/friend/relative wants me to do something so I haven't the time...now I am out of time to make any more excuses.
I can't do this alone, I know how easy it is to slip into excuse mode. I need to do this, I want to do this, but I cannot do it alone.
