James,
You say that "it has actually been more than a year now since my father past away and i feel like im still stuck". It feels to me that when losing your father you lost something else important too. What is it, James? Is it happiness, safety, good company... ...or what? This is a question that only you, James, can answer. When you find the answer, tell yourself that losing your father does not mean losing other important things in your life. While it might have been that your father gave these important things into you life, you can get them from other sources too, like other people, hobbies, work or... ... or just living! The good old life itself!!
When you ask "Am i worthy of life?", you can also ask: Is life worthy of you? What kind of life is worthy of you? What kind of you is worthy of life? I hope you let your imagination fly.. ... high, very high... And find things in your life that are well worthy of keeping, Take hold of these important things and find your worthiness! And when you have found it keep it! I'm wishing you the very best luck! -Purjo
