okay so i am 19 years old, i have not peed myself since i was small. i recently have not been able to hold my pee. i am walking and out of nowhere i have to pee really really bad that i cannot even walk. i peed myself once while i was sleeping, i didnt even feel it until i woke up and a second time as i was walking to my car. i tried my hardest to hold it in until i got to a bathroom but i was unable to even move 3 feet. on other occasions i get the urge to really pee but i leak a bit and am able to continue walking until i get to a bathroom. i have always been able to keep it in and i am scared i have a problem now. please help. Thank you.
