That attitude is probably the reason you're alone.
You might be (unknowingly) projecting a sense of insecurity and dependency on dates, which is totally off-putting. Or if you're not making it to actual dates, you need to put yourself out there more.
Above all, I'd say work on increasing your confidence and living an interesting life even while single. Not only will it make life more fun, but you'll increase the quality of energy you give off, making you more interesting & attractive.
You are very young. You'll find somebody I promise.
