i hear you man, i was at the exact same spot as you a month ago, and i had the time, but lacked motivation. you say your stressed from work and all your life stuff, well try this once when you play, sit down and instead of focusing on making this chord change or playing that song, just sit down an play by ear, no note book no tabs. take what you know and use a different timing, or play part of a song you know with different up and down strokes, for example good riddance is dd uu du, but if you play it d dudu with a some minor changes you get let her cry, so dont try and copy music, just feel your own music, try new things out of your mind and not some one elses. sure note books are great for inspiration but leave it at that, and dont copy them make your own style of music. well that was long and quit un organised o well hope it helps

ps. dont make a routine, routines become tiresome boring and worst of all it feels like work, thus making guitar a chore not fun, just chill when you play
