Keep things nice and light when it comes to interpersonal interactions now -- fluffy, inconsequential and fun. If someone close to you tries to force a discussion about a heavy issue (or any kind of discussion at all, really), firmly deflect them by offering a specific rain check. Assure them that it's not that you don't want to talk about it, it's just that now's not a good time. After all, your good mood depends on it.
