dear diaper_puppy ,
I started getting the syptomes you mentioned in high school , it was a very stressfull time for me .
At the time i went to my doctor and got checked out ran some test and they never found anything wrong with me
(i recomend u get checked out ) , but i would get the sudden intense urge to go sometimes even 10 minutes after going
to the bathroom and when i got to the bathroom barely anything would come out , after living with it for a few years i did some research online
i now know it was my bladder muscles contracting ( i forget what the condition is called ) and when i got to the bathroom
i couldnt relax my bladder muscles enough to let it out . now ten + years later i still have an overactive bladder especially
in stressful situations but ive learned to manage it over the years by keeping calm and not letting the little stuff stress me
out . sometimes breathing techniques helps me calm down .
i hope this helps and if you ever have any questions feel free to ask
take care
