I badly need some help to regain my swimming confidence. I used to swim a lot but cannot do so now. I have lost my confidence.
Returning to the swimming pool can be daunting, especially if it is after a long time or if you were perhaps not the strongest swimmer in the first place. A combination of both of the above can be a certain cause for a loss of confidence.
My advice to you would be to go to the swimming pool but without the intention of actually swimming. Sounds odd, I know, but this is your first step. Maybe even go with a friend or someone you can trust who can hold your hand if necessary.
Your first step when you get there is to get into the water in the shallow end and walk about. Remain in your depth and experience the feel of the water, maybe submerge to shoulder level, but stay within your depth until you feel happy and comfortable.
The next step is holding the poolside and practising holding your breath and submerging your face, maybe lifting your feet off the pool floor. Then maybe try practising some swimming that you remember but with a float or swim noodle for assistance.
The most important thing to remember is to approach it in small steps and progressing at your own pace. Just because you might have been able to swim ten lengths or more once upon a time, it does not mean you will still be able to do it. You will have some psychological barriers to overcome first, which must be done gradually. You never know; it might all come back to you after a few attempts.
What you are experiencing is normal, and if you have some determination, you will have no problems.
