It can indeed get better. How much and in what way - healing is rarely a linear progression - depends on the cause, the extent of damage and what the person is willing to do to correct it. What's done is done, and can't be changed, but it's in your power to do what you can to heal. Diet is essential, as is supplementation and exercise. The mind and body, a united whole, need to both be treated and healed, so meditation, or other forms of stress reduction and relaxation, are essential too. Coming to terms with what has happened is difficult and you may never be OK with what you've lost, but you have much more to lose and can do something about that, if you act. At least that's how I think about it, and I've seen great improvements overall from where I was when it first happened. Best of luck!
