I feel you. My goal is to put some memories in my brain before I can't. I don't want be a stupid Grady fan boy but I love that it mostly works. More so than other brands so far as I know. I don't want to work on the boat, I want the boat to bring me pleasure. That's why I bought it.
I'm 58, I still harbor some hope that maybe a Dr will figure me out and fix me, that would be great, but I doubt it. So the boat is pretty much the only big thing I have in my life. That is not quite right, my wife loves me, but after 22+ years, sex is off the table. My dogs help, oh, man, my dogs, they are why I'm not dead. I love those dogs and they love me. So great. So you take the goodness, whatever that is, you take it.
I'm sorry you have pain, that shit sucks. People who don't have chronic pain just don't know what that is like. It just never goes away.
I hope you go get some fish, power over the pain for a while, have some fun. I bought my Grady to do just that. It is not easy but I have some fun as well. I'm guessing you are Aussie or Kiwi, Kings are what we call yellow tail tuna, right?
Hang in there, pain sucks. Catch some fish.
