Perhaps 'The Lonely Path'. This can be a story of someone who is isolated either by choice or by circumstances. They face their tragedies alone, whether it's dealing with an illness, poverty, or some other misfortune. The title gives an air of solitude and despair which is very tragic.
How about 'The Shattered Dream'? This title implies that someone had a big dream or aspiration which was completely destroyed. For example, a young athlete who has trained all their life for the Olympics but then gets injured in a way that they can never compete again. It sets a very tragic tone right from the start.
A good title might be 'The Heartbreak of Doomed Love'. This title immediately gives the sense of a love that is destined to fail and the pain that comes with it. It implies that the love is tragic and the hearts of those involved will be broken. The word 'doomed' sets a very negative and fateful tone, which is perfect for a tragic love story.
Crying in the Dark. It gives the feeling that the person in the story is suffering alone, hidden from the world, and that their pain is something they have to bear in solitude, which is often the case in a tragic life.
Shadows of a Tormented Soul. This title is quite evocative. The 'shadows' suggest the dark and sad aspects that follow the person throughout their life, and 'tormented soul' directly implies a tragic existence.
I think 'The Shattered Dream' could be a good title. It implies a life full of broken hopes and unfulfilled desires, which is typical of a tragic story.
For a tragic love story, 'The Shattered Dream of Love' is a good title. It implies that the couple had dreams of a future together, but those dreams have been broken. 'Love's Silent Scream' can also be a title. It gives the sense that the love is in pain but can't express it fully. Another title could be 'The Endless Lament of Love', which shows that the love is full of sorrow and the lament goes on and on.
Some title ideas for a tragic love story are 'The Love That Couldn't Be'. It's simple yet effective in showing that there was some obstacle that prevented the love from flourishing. 'Love's Sorrowful Farewell' is another good one. It gives the impression that the lovers are parting in a very sad way, which is often the case in tragic love stories. And how about 'The Tragedy of Unrequited Love'? Unrequited love is often a source of great pain and can lead to a very tragic story.
'A Love Doomed by Destiny'. This title emphasizes the role of destiny in the tragic love. It implies that no matter what the lovers do, their fate is already sealed. It might be because of a family feud, a pre - arranged marriage to someone else, or some other unchangeable circumstance that stands in the way of their love, making it ultimately end in tragedy.
