Getting weaker weekly

Its been prwtty hard to stay optimistic lateky as weak as I have been
Im not lazy and I have evwn tried to exercise some but after 2 mib cant breathe then get so exhaustwd have to sleep a few hours.
I have been eating as much as can and aftwr weeks of eating morw then havw in months before I am unable to gain 1 pound is dwpressing if honest.  I was always the ambitious guy the guy who worked 100+ hour weeks my whole adult life without blinking an eye.  In my 20s was a fighter and trained constantly.  Running 10 miles a day was average for me.  Now I have trouble walkibg to the car, its pretty humbling and extremely frustrating at the same time.
Yesterday was another fathers day didnt see my son again and after 9 years ut still takes its toll on me not one day has passed the whole time I havent thought about him, even more so since his mother died I think
Gotta go fir now til nect tim
