I read your story there and one thing immediately leaped out to me. Isolation. You isolated yourself from your family and your friends. You removed your emotional support structure and then went full burn in a high stress endeavor for an extended period of time. Nobody not even extreme introverts can survive emotionally without a social support structure. You're feeling the aftermath now. The good news is it looks like you've reconnected with that support structure. You aren't going to start feeling better overnight though. Give it some time and learn from this experience. You need your family and friends support and you need to go at a pace that your health can support. Right now you need to heal and that might takes months. Don't despair when it looks like the healing is going slowly. You will heal and then you can try the entrepreneur thing again once you've recovered.
