overweight gal 65 already lost 17 lbs by swimming had my insurance (santa rosa)

stop daily rides to YMCA. I would like to go any time there is adult swim in small pool at YMCA or laps in the large pool. Reasonable monthly Deal ??? I live off Sebastopol near downtown. Like to get into schedules. Loose more weight continue for stress/high blood pressure reduction & of course look and be fit. Still have 30lbs to go {8 months should work} Not hooked to YMCA if you are able to have guests right now. Am going through a state hearing w insurance...I'm a 65 gal This is before I was ill & gained weight
