Like the other person, I don't care that you s**t yourself, not your fault and if someone blames you for that, it's their bad personality showing and they are not the type for you.
How to stop being so afraid? Acceptance is the only way. You are a beautiful person just like anyone else and deserve love just like every one of us.
There are guys out there who do not care about your problem, good guys, just be open and honest about it, humor works great with this as well and when that special guy comes along, you will know. But like anyone here can tell you, it takes time, don't go for just any guy, wait for the right one.
Wish you good luck and hope you can accept this problem soon and enjoy your life to the fullest.
