I asked the doctors how about my physical conditions when I was having each check-up.

They told me that the bad health indicators from two years ago had comegone back to normal.

I was so glad that I gave up theat high-pressure job

last, I've realized how important life workwork life balance was.

Must be "last year", "last month", "last time", etc, if referring to time.
"At last" if meaning "finally".
"Last" alone here implies it was the final thing you gave up and you're thankful for it having been the last thing.

I, really wishhope I can do it.
