Self image (how you see yourself) might need upgrade. If you’re in a different environment than 3 yrs ago, it might be that you found your purpose there but don’t know where to go after that. It’s like blank slate after all that effort that got you where you were 3 yrs ago.
But it’s doable. It’s not the same but it can’t be because your surroundings are probably different now. Routines are different. I think you’ll find it – or it’ll find you somehow and you’ll do well.
