I've been in constant physical pain and I'd only wish that on my worst enemies, who frankly, deserve it. I live in constant emotional pain, which is awful. Pain isn't a blessing. It's just a very awful part of life that some recieve more than others. My existential philosophy is really grim, but it's what it is. My pain gives me purpose and it makes me strong. I suffer, therefor I am. Feeling nothing wreaks chaos on my mind. All I can offer is to try and focus it. Take your pain and throw it at something. Use it productivly.
