How am i supposed to do anything when always in unbearable pain?

Seek treatment: From a specialist in pain management as soon as possible to see if any medication and/or behavioral intervention can be used to alleviate your suffering.

That is a tough one.: How do you do it? You do it in baby steps. I was in marked, chronic pain for about 6 years after a motor vehicle accident. A number of surgeries later with use of massage therapy - i was able to work past daily pain. I know first hand that it is very hard to work with severe pain. You accomplish whatever tasks you can & you give yourself credit for what you can do - instead of focusing on what.
