Embarrassing Problem : I refuse to use the school... - BASHH
It's actually a really bad plan to restrict urination to the point that you are having accidents. Long term this can lead to UTIs, incompetent bladder, and loss of urgency sensation. The usual things that people do to reduce the need to urinate are not good for your health either, this usually involves restricting fluid intake and / or increasing salt consumption. You can minimise the need by ensuring that you go before you leave home and as soon as you return, but a healthy body will usually need to go between these times. I would suggest you are better off putting your efforts into getting the school to improve conditions.
I see, it's unpleasant but not actually a health risk. The thing then is to try to work on your aversion. There are things you can do to help, like using anti bacterial wipes, maybe get some of those single use seat covers, or the shoe covers you get in swimming pools if the floor is always wet. In all honesty, it sounds like you may need some assistance as it could be extremely inconvenient long term if you can never use public facilities.
Please please please use the toilet, don’t avoid using it even if you do have to squat even if it means putting toilet roll around the toilet. It’s worth it in the long run, even if that’s not an option maybe speak to your school reception and ask if you could use staff toilets every now and again they may understand if you explain.
I totally understand your situation, I find it impossible to use public toilets due to a condition called Avoidant Paruresis sometimes known as shy bladder syndrome. I started wearing nappies at the age of 12, and I approached my employers to tell them of my condition and I was given a special key to the disabled toilet for my own personal use at work which is very clean. I wear adult nappies whenever I’m out so I don’t have to worry about using any public toilets. Ok I shower regularly I don’t have any problems dealing with my problem in this way, but I’m guessing nappies wouldn’t be a solution for you to go to school in
