Today i felt depressed, but it had been a while

Hi......sorry I just wanted to put this out there, just out of my system in general. I feel like, whenever I think about "going away", and i start wondering what would the people around me think. And today I thought: maybe they see it coming, so they wont care as much...Also I got mad at a friend for not seeing how depressed I was, but its not their fault, its mine. And now I think: am I even worth the trouble? Anyways, thats me, probably going to leave in a bit
