I'd say don't copy but DIY.
See, your issue is "whenever i play, it's sounding the same more or less the same then usual" so.. it sounds like you are having trouble getting your own voice and your new material sounds stale - you need to get inspired!
Find recording software, easy to find them free ones, and start doing your own stuff...
Listen to material for inspiration so you can steal the vibes not so much the licks. If you notice, its the vibe we are after... not so much the same choice of notes. If you can cop the notes... but not the vibe... hmmm... I'd think its pointless and that is where the "you're just a clone" comes in.
Knowledge of the fretboard is necessary so you can comfortably and
naturally utilise the entire span. There's no need to learn every mode and every scale in all positions but it will sure help. There is a need to be comfortable though - so start playing stuff high up the neck, an area many don't utilise a lot.
