Have to steel yourself, dude. If you feel the humiliation and embarrassment washing over you, then imagine it just doing that. Like water it might surround you, but will flow off you, it can't soak you through. You can stand in the rain and ignore how the drops run down your skin, and how the wet clothing cold at your skin, you can ignore humiliation too, and go through the situation calm.
Later you might feel like burning by it, but then you are alone in your room and doesn't matter anyway.
Frankly you can practice it with the rain as well.
