help out a stranger (what easy guitar songs should i learn?)

i think that im decent at playing my guitar. im not SO amazing but im not so bad. I can play all my basic chords, i can play all my barre chords, and i can play about three songs. BUT the thing is.. i genuinely dont know what else to learn. everything else would be too hard or too easy!!! im REALLY annoyed cz i dont want to stick playing a few songs for MONTHS.
