I think what you are trying to say isn't really a form of masochism, to me it's basically you striving to be pleasing and to please your Master.

I would think that others go through the same thing as well. It's the waiting that makes you more edgy. It is a self infliction that you do to yourself, and I don't really know what you can do to make the waiting better.

I at times used to feel that way, but I have since learned not to worry about it. Regardless as to how long I wait for a response, it's not going to change. It's learning how to deal with patience, waiting and knowing that you've done your best.
