I currently work in information technology, which (long story short) I sort of stumbled into early in life and as it compliments my social anxiety rather nicely (very little interaction with people, if at all, on a daily basis) I've stuck with it for much of my adult life.

However, doing a recent evaluation of my interests, I've learned that's not what I actually have a passion about. I'm good at it, but I have no interest in becoming better at it, or learning more about new technologies, which is a bit of a death bell for future career progression.

What I do want to switch to is medicine, in particular, a focus on nursing within internal medicine/gastroenterology.

Just thinking about this is unfortunately absolutely overwhelming and almost like a knock on my back with all of the feelings of not being good enough, change being hopeless, and generally feeling locked in a field I've been in for a decade now. It feels like a far-off mountain towering over me, and my feet are meanwhile locked deep in cement.

How can I work myself out of these feelings/thoughts and generate the motivation necessary to make the switch without being defeated by depression before I can even take a step forward?
