@Cool Jama, just facts:
1. Your post in a few minutes already has many replies. Wazua is a family of many - people care.
2. Sadness affects us all. Depression is a medical condition and affects the best of us - get help.
3. There are at least 5 people right now, who have no job, don't have your skill or natural talent, didn't have money to go to college, and lost a close one this year. Yet they think they are blessed - life is tough but they are tougher.
4. You need to rediscover your inner spirit, your passion for life! No child, in all their innocence, would say "I am anything but cool and I am a failure". I agree with @leona, Joel Osteen would be an inspiration, or a priest, or a mentor, or a book...
5. If there was an employment opportunity that offered you lower pay for something you are passionate about - take it, by all means take it!
When you take your walk, out of the office to just go somewhere, take a moment, look around and try see the sadness around you - reach out and help someone. Then take another moment, and a deep breath, and see the beauty around you.
