If I give up hope, I might as well throw myself off a tall building
You don’t have to give up, you can be a realists. But what you are doing is o.k. if it works with you. We all cope in different ways. The important thing is not to give up nor throw yourself off a tall building. Nor, for that matter, a short building. Hang there. When they come to get your hide, Make them pay for it. We are all in this together.
