Mentally under-stimulated

I have 3 more weeks of summer vacation than my family. It sounds nice, but I’m reality I feel like I’m loosing my mind. I’ve been trapped at home, alone with nothing to do at all. None of my friends are home and my parents can’t work from home. I’ve started loosing my appetite, become hypersensitive to sound, gotten hung up on things, extremely lonely, but at the same time I don’t want to bother anyone with myself. My hobbies won’t click, clay hardens in my hands, can’t draw because my fingers are constantly shaking, video games are tiring instead of fun, running or just going to the gym doesn’t feel the same. I am so jittery and at the same time tired. I would rather be at school than at home. I sleep horribly and feel like I look so skinny and fat at the same time, I can’t explain it. I haven’t talked with anyone outside of my parents or brother forever, and when I finally got a plan to meet one of my friends and it got rescheduled: I almost started sobbing. I have to have someone else in charge of my schedule or I’ll end up going crazy.
