Summer and how im doing

I haven't really done anything this summer at all. Ive never felt so awful before. Like i feel so dead on most days so like i don't know why i feel horrible. I feel like a living corpse. Just stuck being here, rotting in my room and when i try to go outside i'm quickly overstimulated and I have no motivation to do anything at all.... Maybe i'm just a loser lol But i've never felt so depressed before. Like i haven't done anything this summer and i would usually travel to another country or something. I visited Punta Cana last time and enjoyed it. ( I have a big fear of planes so i'm kinda happy i'm not on a plane. I feel like i'm stuck in a loop. I have nothing to do and i feel like a mistake for it.... Kill me pls
