I'm fairly new to guitar and have only been playin for about half a year and I dont know what to do next? Im not amazeing by any means and know anything about theory what so ever, any suggestion on stuff I need to learn or maybe something helpful to know or just good songs to learn to increase my skill at playing?

maybe try some blues soloing? learn the pentatonic scale and get some jam tracks online and just play around abit.

or you can try to learn some really hard fingerstyle songs a la tommy emmanuel.

Try to learn a song by ear. This is called transcribing. It'll be slow and hard at first, but keep at it. Playing by ear is a useful little skill.
