Sick of being made fun of

Long post sorry

For my whole childhood up until I was probably 14-15 I would wet the bed. Not every night but often. I would be made fun of when I did use the bathroom because my urine stunk. I didn’t have a mom who was on top of my health or cared enough to ask what the issue was. I remember it would hurt to go pee so I would hold it a lot. It wasn’t until I was 18 and ended up being pregnant and was able to get free insurance that I learned how prone I was to UTIs. I wasn’t even fully sure what a uti was. To this day my cousins will bring it up and laugh and laugh about how I used to wet the bed. They tell people I bring around that I barely stopped last year which is an exaggeration but 15 is old to be wetting the bed so they think it’s hilarious. I want to cry but instead I get angry and that doesn’t stop them. I don’t know what to do at the point. I’m hurt that something I’m so ashamed of is being thrown in my face. I guess I’d just love some advice on how to handle this. I’m 22 now.
