Don't Drown yourself with others misery. This whole thing is hard enough living with and coping with pain. Nothing can be improved by feeling badly about it. Find something positive to do. Do you meditate, do yoga, Tai Chi or some other form of mental exercise? They can really help. Perhaps try this. Picture your pain for our pain or everyone's pain as a person. See that person standing in front of you. Say to that person I love you and I forgive you. If it feel stupid do it again. Do it over and over until you actually mean it and you actually believe it. Do the same thing with anyone or anything that tends to depress you. This technique is really intended for dealing with your enemies, actual people you can identify but it might just work on a situation as well. If you want to know more about this kind of approach, Google Spring Forest Qigong and read a little bit about it. It can be a lifesaver.
