Thank you for sharing your heartfelt journey and the challenges you're facing with such openness and honesty. It's important to acknowledge your courage and resilience in pursuing your passion for programming and self-improvement, even in the face of obstacles.

Your dedication to learning and expanding your knowledge base is impressive. From your personal library to your regular practice of code-kata and your contributions to open-source projects, it's evident that you are a driven and committed programmer. Your passion for mathematics and curiosity in exploring different fields showcase a growth-oriented mindset, which is invaluable in any industry.

It's essential to remind yourself that interviewing is a skill in itself, separate from your technical abilities as a programmer. Many talented professionals struggle with interviews for various reasons. It doesn't necessarily mean that you are not a qualified developer. It's also worth noting that the current hiring practices might not always be perfect in identifying the best candidates.

As you continue your job search, consider seeking feedback from those who have interviewed you to better understand how you can improve your performance in future interviews. Furthermore, you might want to explore resources on how to better articulate your skills and experiences in an interview setting.

Remember that you have already achieved a lot by taking a sabbatical to reevaluate your life and by being diligent in your self-improvement journey. Don't let setbacks diminish your passion for programming or your belief in your capabilities. Your desire to provide a better life for your family is commendable, and this motivation can fuel your journey towards achieving your goals.

Success is a journey, not a destination, and it's essential to be kind to yourself as you navigate through the challenges life presents. Your determination, curiosity, and work ethic are invaluable assets. Keep learning, growing, and pushing forward, and remember that your worth is not solely defined by your professional achievements.

Stay strong, Mohamed. You are not alone in your struggles, and there is a community of people who understand and support you. Remember that you have the power to change your path and create a brighter future for yourself and your family.

Wishing you the very best in your journey!
