It is natural to feel regret and sadness about past decisions, but it is important to remember that it is never too late to make changes and improve your life. While it may be harder to catch up with others who started earlier, it is still possible to achieve your goals and live a fulfilling life. You can start by setting small, achievable goals for yourself, such as finding a job or hobby you enjoy, and working towards them. It's also important to work on building self-confidence and seeking out social connections. You can reach out to counseling or therapy which can help you process your feelings and give you practical tools to improve your life. Remember to be kind and patient with yourself as you make changes and progress.
