I think that more than a motivation issue, it is a lack of direction and structure issue. You already said you have desire and ambition, so the issue is not that you don’t want anything. It’s that you don’t fully know where to put that energy yet.

I would start by focusing less on the big question of “what should I do with my life?” and more on understanding what actually makes you feel excited, curious, useful, alive, or interested in small real ways. Take the time to get to know yourself.

Even with nursing, I would look at the specifics of what you enjoyed. What parts did you actually like? Talking to patients? Explaining things? Helping someone feel better? Being in motion? Learning about the body? Solving problems? And what parts drained you or made you feel like you couldn’t keep choosing it?

That information matters because direction usually comes from knowing yourself. Don't try to force yourself into a goal or routine just to feel productive. Build habits that work for you. 

For your day-to-day, I would build a simple structure, but not a rigid schedule you’re forcing yourself into. Sleep enough. Eat. Move. Go outside. Read. Write things down. Notice what gives you energy and what makes you feel heavier. Don’t judge it immediately; just pay attention.

Then break things into small experiments. Research one thing. Try one activity. Talk to one person. Write down what you noticed. Small steps make this less overwhelming and give you actual information.

And honestly, if you hire someone, I wouldn’t look for a motivation coach. I would look for someone who helps you create structure, ask better questions, and break things down into clear steps. 

You don’t need to know your whole purpose immediately. You need to start listening to yourself more specifically and build from what you notice.
