Navigating life can most definitely bring on times where the stress is great and we can feel very alone. People who have achieved recognition have faced challenges that were hard and often they felt very alone as you are describing.

One of the things successful people do is they read about the lives behind successful people because as they do so they learn about things these people faced that really tested them and how they had even failed but committed to keep going and learning.

Part of surviving and growing is learning how to navigate these challenges you are facing and not having a parental type presence there to help.
