short while or something

My ex girlfriend said that everything lasts for a very short while and then ends. (I broke up with her after 5 months, the day after prom, poor planning on my part, but it's what she deserved.) Maybe this is my short while. i'm turning 17 soon and ive never felt like a person, i've always felt consumed. ever since I was young, its been this rotted feeling, covering my skin, filling my lungs, dragging me down, chaining itself to my legs and dragging me down. "Life moves on" but it doesn't really. "You'll move on" but you won't really. i shouldn't be allowed to feel bad. i ended it, she deserved it, etc. but still. i'm selfish. we all know that. i love to overstay my welcome, make my short while a long while. who knows!
