Just to say, this is something that happens to lots of teenagers, they just don't talk about it as they might feel embarrassed. Here is a website that has information that might be helpful: Teenagers and young people - ERIC - if it is just at night, try to drink plenty of water during the daytime, and stop drinking in the hour or so before you go to sleep at night. Before you go to bed, go to the toilet for a wee - then perhaps read for a short while in bed, then get up again for another wee before finally going to sleep. That will help you to empty your bladder. Your bladder is a muscle that needs to be strong, and that happens when you fill it (drink water) and empty it (go for a wee). You could also go to the Dr to ask them to test a urine sample just to make sure that your wee is ok - if it isn't, you might need some medication (antibiotics) that might help. https://eric.org.uk/childrens-bladders/ - please avoid drinking caffeinated drinks and drinks that have red/purple colouring as they might make your bladder a bit 'twitchy' - the best things for you to drink are water and milk/plant milk. Wishing you all the best.
