New (again) to swimming

Hello - this is my first post as I stumbled across this website while looking for workouts. A little bit about myself....I am 44 years old and have been away from swimming (or any kind of real phsycial activity) for a number of years. I swam competitively as a youth, in high school and in college. I was swimming with a masters team, but felt the workouts were geared towards those interested in competing. The rest of us were just sort of thrown in a lane together!! 4 months ago I decided to lose weight and get back in shape. Although I walk almost daily, I missed swimming. I just discovered that the local community pool has lap swimming 3 days a week and water aerobics 2 days a week. Perfect!! The first week I swam the following: 200 free swim; 2 free kick 200 back swim; 200 back kick 200 free swim; 200 free kick 200 *** swim; 200 *** kick 200 free swim; 200 free back The problem is....where to go from here. I am looking for any advice, suggestions, etc. on where to take my workouts from here. My goal is continue on my own through the summer, take a swimming class (where I can do laps) at the local community college, and then join the masters program (when I feel I can keep up). I am hesitant to join the masters now, as I feel I may get discouraged. As I said, any suggestions, advice, workouts anyone can offer would be greatly appreciated.
