I couldn't go to see my friends or to go outside and enjoy anything because I was in constant pain. Eventually, I had depression due to lack of joy in my life and lack of going outside. If you are stuck with physical pain and it causes you to be non-mobile, then you are going to have mental and social issues. Hope this helps :)
