How do you get over the feeling of hiding away from the world?

The high potential promised individual drop to barely getting by day, without any of the promised results, academically or career wise.

I feel like I let down myself, my belief in myself, my confidence, self-esteem, which were tied to the well achieving individual, and ofcourse my parents or people that knew me and were certain I would be in a good place in the future,

I hide from the world, hide from people, because Im stuck in my head, of no progress, of disappointment, of wasted potential, of no real skills that I should be having from my studies because I didn't study, and I really don't know if I can get myself to complete my degree, not for namesake but with actual skills,

If anyone went through the promised child to wasted potential pipeline, how did you deal with it while it was happening to you?
