Hey was wondering if there is any way to pause my account, so like if I know I am not going to be able to process requests for a couple of weeks, I won't end up with a bunch of requests that I am not available to answer?

Yes, you can put your account on Vacation Hold...go under My Account and there will be a drop down menu and you can select Vacation Hold and then you can set how long you want it on Hold.

If you have books on your WL that you have credits to cover you can put them on AutoRequest and you'll still get them, otherwise you won't get offers for books but, will continue to move up the WL line until you get to #1 and then you hold that position until you take your account off Vacation Hold.

Is there any way i can delete my account?

Brooke, in the Help Documents (use the Help Center tab at the top of the screen) you can search "close account" and the instructions will pop up, including a button you can select to contact PBS and ask them to close your account for you.  I'm sorry that you don't plan to stay. :(
