At least you aren't 19. You'd be surprised how many under 25 year olds complain that they'll NEVER find the love of their life...or are in unhealthy relationships but can't leave because what if they NEVER find love again?
But, in all honesty, poly can be harder. Everyone thinks it's easier, cuz you can date anyone right? But as soon as you say you're poly, people freak out. Or can't handle not being your one and only. Or...whatever. It limits your dating pool considerably.
Be patient, you'll meet the right person. But be proactive, too. Build your life in a way that accommodates being poly
Also, don't take Polyamory as a basis of how to go about being poly. The shows and books that exist today are usually awful
