I think we all consider security when looking at careers- it’s difficult not to. The problem is when job security becomes the only considered factor. That ends up creating a lot of anxiety, and an anxious state is the worst kind for making decisions.

Are you making videos right now? If not, you can start doing that just for fun, and just the process of it might soothe your anxiety. You don’t have to think about the money- just enjoy the process of making the video. And it’s a common belief that artists/creatives don’t make any money. But if you think about it, film/TV are very large industries, so all those people working in it must be bringing in a paycheck somehow. How do you feel about finding some people in the videography (correct term?) field to talk with? Just a chat- you can consider it an exploration. You might even find an amateur group/meetups, and just enjoy doing that. If you really do like some aspects of medicine, perhaps you can even consider combining your knowledge of the field with your video editing skills.

From what you’ve written, I think  that aside from finding your niche, you really need some simple enjoyment and fun in your life. It might even help to take a short trip (or plan one for the future) to clear your head. Hope this helps 🙂
