Nia, you can do it!! Don't feel embarrassed. Get private lessons - I strongly recommend them.
I know someone in my gym (a woman in her 40's) who could not swim at all (not even doggy paddle) go on to finish an Ironman!! No doubt, she worked very very hard, but she got into the best shape of her life and completed the race! It took her one full year of training, but that's pretty darn good if you ask me considering she couldn't swim at all!!
You can do it! If there's a will there's a way right?
Trying to be the person my dogs think I am.
