Second male lead syndrome.

First time writing on here, please have mercy. Anyway, I always feel bad for the 2nd mls, they remind me so much of myself it physically hurts. Not being someone's first choice (whether it be friendship or love) is really starting to take a toll on me. Watching everyone have someone to carry their burdens with while i have to piggyback mine by myself. Every time I see the second mls get rejected, it reminds me that I'm always just the friend, never the lover.
