You've experienced a serious health problem. I hope you live the healthy life you desire.
Changes like these are turning points; nothing is ever the same again. There will be times when things aren't going well, when things aren't going well, but it takes a strong will to prevent this.
You're doing everything you can to improve your current circumstances. I believe you will succeed.
Succeed or fail, I think at the end of the day, life is just about trying to meet a meaning.
