My head hirts just looking at this... but this is caesar code.

Ok so... it reads:
IT FEELS LIKE NO MATTER HOW HARD I TRY, I END UP FEELING MORE AND MORE DEPRESSED WHEN IF FEELS LIKE NO ONE LIKES MY STUFF. YESTERDAY WAS MY LONELIEST DAY AND SECOND TIME C U T I N G MY HAND. I'M NOT SUICIDAL, JUST LONELY. I DO WANT TO THANK THOSE WHO MADE ME FEEL LIKE I WAS A PERSON AND NOT JUST A USERNAME ON A SCREEN. PLUS, I WANT TO FOCUS MORE ON SOME OF MY SCHOOL WORK AND HOBBIES I WANT TO DO, SUCH AS FILMMAKING. IDK WHEN OR IF I'LL BE BACK BUT WE'LL SEE. HOPE YOU GUYS ENJOY MY MEMES AND DRAWINGS I MADE. PEACE FROM INADEQUATE!

Ok. First off, you're not lonely. Especially if it's being depressed (count me in). Secondly... well, see ya later mate!
