No, you don't.

I think it might help to change the way you look at this. It is not only a problem but also a big chance to find something that fuldills you again. I went to the same situation but with lot less savings. It was damn hard and still isn't all sunshine, but i do not regret leaving my boring well paying job at MS for a second. Problems will occur but they are also solved on the way.

Read Books on the topic, make a solid plan, and then learn to trust in yourself and let go. Might sound oversimplified but sometimes you have to make a change in order to get what you really want in the end. You're not alone in this. There were thousands that did the move. Best of luck.
