For myself 
I taught myself to swim around 6 year's ago. I used to have a fear of water and breathing problems. . Asthma as a kid which evolved into panic attacks the minute I felt my breathing was somehow impaired.. so being near the water or in, being out of breath or in enclosed spaces.. too hot etc. Turtle necks are a no go 
Anyway. . 6 year's on and I can breaststroke a mile and go a few times a month. . In fact I really love it.
I have in the last few years been able to use middle lanes, instead of being too scared and having to stay near the edge at all times. I feel I've come along way and honestly enjoy the water. But I still have anxiety over being splashed and cannot swim longer than 45mims- 1 hr max because my neck and back gets sooo sore from the tension of constantly keeping my head above water and not changing techniques. I would in no way consider myself a strong swimmer.
I feel incredibly embarrassed and when I confided in my mother she literally laughed in my face, but I want to pay for some private one on one lessons so I can learn to swim properly and overcome these fears (i hope) in a safe environment and with proper guidance. I feel so cross that she laughed at me.. its her fault I have reached adulthood without this life skill (i have had my children enjoying water from a very early age and want them to be competent swimmers) ..and now feel so utterly embarrassed I'm not sure I can pluck the courage to book them.. will they think I'm utterly ridiculous? ?
This has turned into a rather long post.. sorry!
