Try meditation, going for a walk, anything to help feel better. If you have meds, take the right dose, or if you drink, have a few sips of some booze or drink some tea or coffee. Really, give it an hour and then start being practical. Being in this terrible mood won't make you less dependent or less entitled, and it definitely won't protect the feelings of those who are attached to you. Being in a better mood and doing some practical things to support yourself is the only thing that will. You might have to start small and take things slowly. What is your level of dependency?
