> Got cancer, a new job,new boss in less than a year What do I do now?

Live in the now. Don't brood over your past, don't worry about your future, unnecessarily. You accept it and keep doing what you would normally do. Don't try to find meaning or ascribe some meaning to what is otherwise a natural process of our modern life. You have health issues, you get it treated it and try to live healthier. That's it (what more can you do?). You got a new job. Congratulations. Give it all you got as you would normally do. Your company got acquired, you got a new boss, your job sucks now. Skill up. Fight for your current job or search for a new one. (Also, talk to your old boss and close co-workers). Looking back at your past, or worrying about your future is only useful if it helps your present. Live in the now.
