One of my troubles

One of my hobbies is scuba diving. But I'm the only employee in my department my department's employee is only me.So there are is no one who can fill my shoes for my task. I find it difficult to have difficult time to take time off for vacation. That's why I hardly ever go out for scuba diving. So there are long periods between scubadiving. Each time the moment that I dive into the sea after a long interval, I get a cold feet. Because I've always lost my touch. But immediately, I could knock the rust off.
