Bit late to the conversation, but it certainly seems you have reached the point of FI. Your savings can provide a very reliable and long term source of income; in fact above what most of the people here would say is their value.
So for you it becomes a process of defining priorities and changing what is important in your life. You don't need more money as far as I can tell. You do need to get back to enjoying the quality of life aspects you have sacrificed by working hard over the years. As I have said many times, you may have a job to retire from, but you need something to retire to. That is where you are, you need something to retire to. That can be travel, do some hobbies you never had time for, fixing up your house, vounteering, or whatever you would get some satisfaction out of.
As several have said above, you need to determine your budget, evaluate your risk tolerance, and then just set up an investment strategy that meets those requirements. That is the logical part. You also need to make an emotional adjustment, learning what makes you happy outside of working and the money security aspects of it.
I used to have a handle on life....... but it broke!
