I've learned one important lesson in my life, and I'm going to share it with you. Don't worry about bad things that haven't happened yet. It will save you a lot of anxiety.
If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
Once writing has become your major vice and greatest pleasure only death can stop it. Financial security then is a great help as it keeps you from worrying.
If there is no solution to the problem then don't waste time worrying about it. If there is a solution to the problem then don't waste time worrying about it.
