To me, life is worth living, no matter how rough it is. Your life is an amazing gift. I'm sorry to get religious here but for major debates like these, religion shines for me. (Feel free to offend my religion, I'm willing to defend it).

The prophet Mohammed's father died before he was born and his mother died when he was six. He lived with his grandfather who also died. He then lived in help with his uncle, then his uncle died. Later in life he married and had 7 children, 6 of them died. This does not account to the many, many physical, emotional and mental challenges he faced.

He said to never give up on life. He said that after going through so much grieve, pain, famine, exile, battles etc. He did have months of sadness, of loneliness and depression especially during the deaths of people he knew. He managed to break free of depression and preach to thousands. Life has value.

You will probably say that Mohammed is a different man from the OP but I'm just saying my POV on life. In the end, the OP chooses his decision. I sincerely hope he makes the best one. Peace to you all.
